Our
Strategy
Our objective is to develop
and commercialize our product candidates to treat diseases where the innate immune system is dysfunctional causing or contributing to
the patient’s disease. Innate immune dysfunction can occur for a variety of reasons including genetics, lifestyle, and other factors.
However, age plays a significant role in the development of immune dysfunction. Innate immune dysfunction can be seen in cancer where
Natural Killer (“NK”) cells are impaired and facilitate a tumor’s evasion of the immune system and subsequent disease
progression. Further, immunologically-mediated chronic inflammation causes expression of MUC4, inducing immunosuppressive cells of the
tumor microenvironment to proliferate and protect the tumor from attack by the patient’s immune system. Chronic inflammation is
implicated in neurologic and metabolic diseases where it impairs the innate immune system. Our initial focus is on the treatment of cancer,
Alzheimer’s Disease (“AD”), Treatment Resistant Depression (“TRD”) and an out-licensing strategy. In cancer,
we plan to pursue two parallel development programs: (1) with INKmune we are treating men with castration-resistant, metastatic prostate
cancer (“mCPRC”); (2) with INB03, we plan to develop pre-clinical data in cancers that express MUC4, a mucinous polyglucan
on the surface of some epithelial cancer cells with a goal to out-license the program. MUC4 expression appears to predict resistance to
immunotherapy including women with MUC4 expressing HER2+ breast cancer and potentially other MUC4 resistant cancers.
Our third drug candidate,
XPro1595 (“XPro”), targets Alzheimer’s Disease and TRD. XPro for AD has completed Phase I trials and a Phase II trial
is open in, UK, EU, Australia and Canada. XPro for TRD is being prepared for Phase II trials and will start after the current AD global
Phase II trial has completed recruitment. In early 2023, the Company also announced pre-clinical data in Duchene’s Muscular Dystrophy
(“DMD”) including new intellectual property for the purpose of trying to seek partnership for the development of this program.
DMD is an X-linked genetic disease that occurs most often in young boys. People with DMD do not produce dystrophin, a protein necessary
for normal skeletal muscle function. The patients develop weakness of skeletal muscles initially seen as weakness in standing and walking.
Over time, the disease progresses forcing the patient to be wheelchair bound by early teens. The patients typically die young due to respiratory
and cardiac failure before they reach thirty years old. Therapies for DMD delay progression, there is no cure.
The
overall principal components of our business strategy to achieve these objectives are to:
●
pursue development strategies and regulatory approval
pathways that allow us to expand the treatment of oncology patients with our lead product candidate INKmune;
●
pursue pre-clinical development strategies to facilitate out-licensing
INB03;
●
pursue development strategies
and regulatory approval pathways that allow the treatment of neurodegenerative diseases in patients with our lead product candidate,
XPro;
●
Pursue
development strategies with a dominant-negative tumor necrosis factor (“DN-TNF”) compound for the treatment of DMD;
●
adopt
a product development strategy that solidifies our existing intellectual property (“IP”) to prevent competition and expand
our IP suite into related immunotherapeutic areas;
●
provide
clear value propositions to third-party payers, such as managed care companies or government programs like Medicare, to merit reimbursement
for our product candidates; and
●
Collaborate
with other pharmaceutical companies with respect to, among other things, our INKmune and the DN-TNF platform that includes INB03
and XPro product candidates, our DMD DN-TNF candidate and other products that will benefit from development or marketing beyond our
current resources.
Pursue development and
regulatory approval pathways. We believe INKmune, INB03 and XPro may be approvable under pathways that are potentially shorter than
those typically available for drug products based on novel active ingredients, including as an orphan drug under the Orphan Drug Act and
approval under the Food and Drug Administration (the “FDA”) Accelerated Approval Program (see “Government Regulation”).
We have not yet had a discussion with the Medicines and Healthcare Products Regulatory Agency (“MHRA”) and/or FDA regarding
such designation, but plan to do so in the future. We believe the INKmune program to treat castration resistant prostate cancer may qualify
for orphan status. We believe that it would take a minimum of six months to receive Orphan Drug status once we apply for application
and a minimum of 12 months to receive a designation once we submit an application. We might never have these discussions, submit applications
under the Orphan Drug Act or the FDA Accelerated Approval Program or have these applications approved if we do.
1
Adopt
a two-pronged patent strategy. We are pursuing a two-pronged product development strategy that will seek to solidify our existing
IP to prevent competition and expand our IP suite into related therapeutic areas. We are confident that our core in-licensed IP (see
“Intellectual Property”) will allow us both freedom-to-operate and provide robust protection from outside competition. We
will continue to invest in expanding our patent suite. We will also seek to further strengthen our IP position by looking to in-license
IP related to our focus on the innate immune system.
Provide clear value propositions
to third-party payors to merit reimbursement for our product candidates . We are designing our clinical development programs to demonstrate
compelling, competitive advantages to patients and prescribers, and to demonstrate value propositions to third-party payors. We believe
the use of INKmune and/or INB03 in patients with a high risk of tumor progression and death from tumor should prolong survival, improve
the patient’s quality of life and decrease the total cost of care for patients with these lethal malignancies. For example, cancer
patients relapse frequently. Each relapse requires a complex treatment regimen that has decreasing benefits. Treatment with INKmune as
an out-patient may provide a more durable remission and limit the need for treatment-associated hospitalizations. At the patient level,
we believe INKmune, if approved, should improve survival and quality of life. At the payor level, we believe INKmune, if approved, should
provide more predictable costs and outcomes. Therapies for Alzheimer’s disease are needed for medical, societal and economic reasons.
The cost of Alzheimer’s disease to the government is large and growing. Recently approved therapies that target amyloid have a modest
impact on disease progression and are difficult to use due to side-effects in some patients. The cost of AD to families and care givers
is real and burdensome. We believe treatment of dementia patients with XPro, including Alzheimer’s disease, may provide a strategy
to alter the costly dynamic of this disease in society today.
Collaborate
to maximize the value of our technology . We believe there are two reasons for us to enter collaborations with other companies. The
first is the further development of INKmune, INB03, XPro and DN-TNF by either providing additional innovations to the product, including
combination therapy strategies, and/or providing resources to improve the speed and breadth of the development process. The second is
to optimize the commercialization of our products either globally or regionally. The ideal partner will benefit us in both ways.
We
continue to look for ways to utilize our unique capabilities to optimize clinical application of cell therapies. We believe that we have
developed a way to manufacture human mesenchymal stromal cells for the medical research and biotech community that offers large volumes
of high-quality, low passage human umbilical cord mesenchymal stromal cells with minimal batch-to-batch variability. We have established
a reliable supply of human umbilical cords based on our agreement with the Anthony Nolan Cord Blood Bank in the United Kingdom and may
seek additional supplies from US sources in the future. We have developed a validated manufacturing process that reliably produces clinical
grade (“cGMP”) quality mesenchymal stromal cells that we call CORDstrom. The manufacturing process is currently performed
at a contract manufacturing site under the direction of Mark Lowdell, the Company’s CSO. To date, we are supporting a multicenter
academic clinical trial in the UK with CORDstrom. This is a Phase I/IIb trial sponsored by the Great Ormond Street Children’s Hospital
in London treating children with the most severe form of Erythematous Bullosa (“EB”), a disfiguring and sometimes fatal skin
disease that is similar to a second degree burn. INmune Bio is supplying the clinical product for treatment of these patients. The Company
does not know the results of this trial until they are announced by the principal investigators at the clinical sites. We have identified
contract manufacturers in the UK that have the capability to produce cGMP stem cells. We expect the commercial arrangement with academic
laboratories or biopharma companies to be a combination of fee-for-service and licensing that does not require additional investment
by us. We will be opportunistic in pursuing therapeutic opportunities for our own portfolio with this platform in the future if resources
become available. The regulatory path for therapeutic applications of the mesenchymal stem cell products is well established and similar
to the regulatory approval process for other cell therapies. We will only be responsible for regulatory compliance related to manufacturing
of the mesenchymal stromal cells when the product is being developed by a third party. When developing a therapeutic product for the
Company’s commercial portfolio, the Company will be responsible for all aspects of the regulatory process.

Overview
of Immunotherapy for Cancer
The
immune system has two parts, innate and adaptive. The innate immune system is the body’s first line of defense against an infection,
providing immediate, non-specific responses to eliminate harmful cells in the body. Components of the innate immune system include cytokines,
chemokines, macrophages, neutrophils and NK cells, among others.
The
adaptive immune system is often initially triggered by the innate immune system, mounts a delayed response against diseased cells and
plays a role protecting against re-infection. An adaptive immune response is highly specific to a pathogen or antigen and is developed
or learned from prior exposure. Key components of the adaptive immune system include antibodies which bind to antigens and mark them
for destruction by other immune cells, B-cells which produce these antibodies upon exposure to antigens, and T-cells which attack and
eliminate the diseased cells.
The
biopharmaceutical industry has made significant advances in harnessing specific components of innate and adaptive immune systems for
therapeutic use. Some of these approaches are summarized below.
Cytokines.
Tumor Necrosis Factor alpha (“TNF”) is the focus of XPro and INB03. TNF biology has four elements that include two
cytokines, soluble TNF and trans-membrane TNF (“sTNF” and “tmTNF,” respectively), and two receptors, TNF Receptor
1 and 2 (“TNFR1” and “TNFR2”). The biology of TNF ligation of TNFR varies dramatically based on what elements
of the TNF system that are used. sTNF binding to TNFR1 is responsible for inflammation and cell death while sTNF binding to TNFR2 promotes
proliferation of regulatory T cells (“Treg”). In patients with advanced cancers, increased sTNF is not favorable to long-term
survival because it promotes epithelial-mesenchymal transformation and metastasis while making the tumor microenvironment more immunosuppressive
promoting resistance to therapy. In the CNS, sTNF promotes neuronal cell death, demyelination and synaptic pruning while tmTNF promotes
nerve cell survival, improves synaptic function and stimulates remyelination. In brief, sTNF is the “bad” TNF and tmTNF is
the “good” TNF. In patients with cancer, infection or neurologic disease, blockade of tmTNF function has negative consequences
such as immunosuppression, increased infection, synaptic dysfunction and demyelination.
One
of the early applications of immunotherapy is the use of cytokines, including interferons and interleukin-2 (“IL-2”). Interferons
are molecules that inhibit the growth and replication of diseased cells and stimulate innate immune cells to attack them. They have been
used as standard of care for hepatitis B and C and multiple sclerosis, and to a lesser extent, as treatment for certain cancers, including
chronic myeloid leukemia, cutaneous T-cell lymphoma, myeloma and non-Hodgkin’s lymphoma. However, the use of interferons has generally
decreased over the years due to serious adverse events ( e.g. , flu-like symptoms and dramatic weight loss) and introduction of
new therapies with higher efficacy, better safety profiles and more convenient administration although Alpha-interferon remains the treatment
of choice for some hematological conditions such as polycythemia. IL-2 activates T-cells and NK cells to attack diseased cells. IL-2
has been used to treat select cancers, but due to its relatively poor safety profile, physicians often only resort to this therapy for
the most advanced settings.
Antibody
therapy. Antibodies exist in three formats: monoclonals (“mAbs”), oligo/polyclonal and antibody-drug conjugates.
mAbs represent an effective therapeutic modality and are important to the treatment paradigm of various diseases. Drug manufacturers
have leveraged mAbs’ ability to induce an antibody-dependent cell-mediated cytotoxicity, or ADCC effect to develop better treatments
that prolong survival and quality of life of patients. In addition, mAbs designed to inhibit specific checkpoints in the immune system
have overcome in vivo immune suppression and the resulting immune responses have led to profound therapeutic benefit in some patients.
However, the degree of efficacy of these therapies is heavily reliant on the immune system of patients, many of whom are severely immuno-compromised.
In addition, mAbs are manufactured through a complex process that requires purification of cell products created from a cell line. Polyspecific
antibodies, for example bi-specific antibodies, are able to target more than one antigen. These are often used to bring and effector
T cell in contact with a target cell. Antibody drug conjugates are mAbs attached to a toxin, chemotherapy or radio therapy that delivers
the cancer killing payload directly to the cancer.
3
Dendritic Cell Therapies.
This approach is designed to indirectly stimulate a patient’s T-cells by leveraging the role of dendritic cells in presenting antigens
to T-cells. Cancer vaccines are the most common application of dendritic cells. FDA-approved dendritic cell therapies such as PROVENGE,
which entails collecting monocytes from the patient, maturing them into dendritic cells, “loading” ex vivo with the
patient’s cancer antigens, and then re-infusing in the patient. Currently, this process is cumbersome and expensive, and again,
relies on an intact and effective immune system of the patient. There are additional ongoing preclinical studies and clinical trials being
conducted by our competitors aimed at addressing certain of the limitations associated with this approach. To date, current clinical results
of dendritic cell therapies have been mixed.
CAR-T
and TCR Therapies. T-cells recognize diseased cells by receptors engaging with antigens that are present on or inside the diseased
cells. CAR-T therapy entails genetically engineering T-cells to express synthetic CARs that direct T-cells to antigens on the surface
of cancer cells. TCR therapy modifies T-cells to express high-affinity tumor specific TCRs that recognize intra-cellular antigens that
must be presented on the surface of target cells. In early clinical trials, CAR-T and TCR therapies have demonstrated impressive anti-tumor
activity in a narrow spectrum of hematologic cancers and garnered significant attention by research institutions and biopharmaceutical
companies. We believe a key limitation of adaptive autologous immunotherapy is the need to retrieve non-compromised immune cells from
a cancer patient which requires a complex and costly manufacturing process to develop the therapy. The complexity of this personalized
process is reflected in the price of the two approved therapies. CAR-T therapies - tisagenlecleucel and axicabtagene ciloleucel for advanced
leukemia and lymphoma respectively. The cost of a single therapy is many hundreds of thousands of dollars. As a consequence of this need
to harvest active T-cells, current Phase I clinical trials for autologous CAR-T cell therapy in large part enroll patients from highly
selected, often relatively early-stage disease in a narrow spectrum of cancers, including bulky hematological cancers. In addition, Phase
I clinical trials of CAR-T cell immunotherapy have reported severe adverse toxicities of cytokine release syndrome and neurotoxicity,
requiring hospitalization, pre-conditioning and, in some instances, intensive care unit admission following side effects associated with
cytokine release syndrome. As a result, though our competitors continue to develop their CAR-T and TCR product candidates with the goal
of addressing certain of the limitations associated with these approaches, we believe these serious challenges may limit their potential
and use in a variety of indications, including solid tumors.
Checkpoint Inhibitors.
Immune cells express proteins that are immune checkpoints that control and down-regulate the immune response. These are best defined
in T lymphocytes and include PD-1, CTLA-4, TIM-3 and LAG3. Tumor cells express the ligands to these receptors. When T cells bind the ligand
to these proteins on the tumor cells, the T cell is turned off and does not attempt to attack the tumor cell. Thus, checkpoint inhibitors
(“CPI”) are part of the complex strategy used by the tumor to evade the patient’s immune system and are responsible
for resistance to immunotherapy. Biopharmaceutical companies have successfully developed CPI that block the receptor/ligand interaction
to promote the adaptive immune response to the tumor. Six CPI are currently approved, pembrolizumab, nivolumab, atezolizumab, avelumab,
durvalumab, and ipilimumab for a wide variety of solid tumors including melanoma, lung, bladder, gastric cancers and others. More CPI
are in development and more tumor types will be added to the list of sensitive tumors over the next years. CPI have become the backbone
of cancer therapy and are expected to be the best -selling class of drugs in the future.
NK
Cells. NK cells typically represent approximately 2% to 13% of circulating lymphocytes and are a critical component of the immune
system responsible for innate immunity. Unlike adaptive immune cells, they are ever present and ready to attack, having the inherent
ability to detect and eliminate diseased cells without the need for antigen presentation, which is why they are called “natural
killers.”
NK
cells bind to stress ligands expressed by the diseased cells and directly eliminate them. This binding induces NK cells to release cytokines,
including, interferons and GM-CSF, which are integral in recruiting additional innate and adaptive immune responses by the host. NK cells
also represent a critical effector cell for ADCC, whereby target cells bound with human antibodies, whether made by the patient’s
body or administered, are selectively destroyed by the NK cells.

Our
Innate Immune Dominant-Negative TNF (“DN-TNF”) product candidate
We renamed XPro, which we license
from Xencor, to INB03 when it is used for cancer related indications. We will continue to call the drug XPro when used for treatment of
neurologic and psychiatric diseases, including Alzheimer’s disease and TRD discussed below. INB03 and XPro are the same drug with
different names. INB03 neutralizes soluble TNF in the tumor microenvironment (“TME”). Neutralizing sTNF in the TME has two
main effects – decreases expression of MUC4 by the tumor and converting the immunosuppressive cancer promoting TME that promotes
tumor growth to an immunologically active TME that promotes tumor cell death. INB03 alters the immunologic environment of the TME to promote
tumor killing. INB03 decreases proliferation of MDSC, promotes recruitment of cytotoxic T cells to the TME and may convert immunosuppressive
tumor macrophages into tumor phagocytic macrophages. In murine models, these changes make the tumor reverse resistance to treatment with
immunotherapy alone or in combination with tyrosine kinase inhibitors (TKI) such a lapatinib and tucatinib. MUC4 expression is increased
by sTNF produced by the tumor. MUC4 causes resistance to trastuzumab therapy in HER2+ breast and gastric cancer cells by preventing binding
of trastuzumab to HER2 by steric hinderance. By neutralizing sTNF with INB03, decreases MUC4 expression to allow trastuzumab to bind HER2.
The importance of trastuzumab based immunotherapy in the treatment of HER2 expressing tumors has increased recently due to the success
of trastuzumab-deruxtecan (Enhertu, TDxd). TDxd improves survival in women with metastatic HER2+ breast cancer in both high and low HER2
expressing tumors. MUC4 expression inhibits the TDxd tumor killing in a murine model of HER2+ trastuzumab resistant HER2+ breast cancer.
The mechanism by which combination of INB03 with TKI improves efficacy over TKI alone remains under investigation. By using INB03 as part
of combination therapy for cancer, we believe the patient’s dysregulated immune response, a hallmark of cancer progression and resistance
to therapy, to be converted to a coordinated immune response that can overcome resistance mechanisms to immunotherapy in MUC4 expressing
cancers. These immune responses have been studied in at least two animal models. In a murine model of an inflammatory cancer, where 3-methylcholanthrese
is given to mice in a subcutaneous injection that causes the development of multiple cutaneous fibrosarcoma. This model was developed
by Y Akamatsu in 1967 while working at the National Cancer Institute of the NIH. In research published by Professor Nikola Vujanovic in
Cancer Immunology Research in 2016, treatment with INB03 resulted in smaller and fewer cancers with increased survival.
INB03 is an engineered PEGylated protein that neutralizes human soluble TNF, a human inflammatory cytokine that is increased in patients
with advanced cancer. By specifically neutralizing the cytokine, there is decreased phosphorylation of STAT3, an essential step required
for the proliferation of the MDSC population, and secretion of the immunosuppressive cytokines. The combination of decreased MDSC proliferation
and decreased immunosuppressive cytokines allows the immune system to respond to the tumor. This data was published in an article entitled
Inhibition of Soluble Tumor Necrosis Factor Prevents Chemically Induced Carcinogenesis in Mice in Cancer Immunology Research in Cancer
Immunology Research, 2016. In summary, INB03 functions as an innate immune system checkpoint inhibitor by eliminating the population
of MDSC that provides an immunosuppressive shield protecting the tumor, the patient’s immune system is able to function normally
to the benefit of the patient – it can attack the tumor. TNF plays an important role in breast cancer (Schillaci R, Front. Oncol.,
22 April 2020 https://doi.org/10.3389/fonc.2020.00584 ). In a murine model of trastuzumab resistant breast cancer using JMIT-1 cells,
a human cell line of HER2 positive breast cancer resistant to trastuzumab placed into immunocompromised mice, INB03 downregulates MUC4
from the surface of the JMIT-1 HER2+ breast cancer cells to allow the trastuzumab resistant cells to become trastuzumab sensitive (Figure
A from Bruni, NYAS 2020) to decrease tumor growth (from Schillaci SABCS 2018, Figure B). JMIT-1 cells are also resistant to lapatinib,
a TKI inhibitor used as a second line therapy in women with trastuzumab resistant HER2+ breast cancer. The addition of INB03 to lapatinib
in the animal model reverses lapatinib resistance in part by decreasing expression of MUC4 (from Bruni NYAS 2020, Figure C). In addition
to decreasing resistance to trastuzumab by decreasing MUC4 expression, INB03 decreases the immunosuppressive tumor microenvironment (Schillaci
SABCS 2018, Bruni NYAS 2020). Recently, Dr. Schillaci reported the MUC4 expressing triple negative breast (TNBC) cancer patients have
a worse overall survival. (Schillaci SABCS 2021). More recently, Schillaci has shown that MUC4 causes resistance to trastuzumab ADC (trastuzumab-durextecn;
TDxd). Combination therapy with INB03 overcomes resistance in this breast cancer model. These data may be relevant to all tumors that
express HER2 or MUC4 including upper gastrointestinal malignancies such as gastric and pancreatic cancer. We believe MUC4 expression is
a biomarker of resistance that may improve therapeutic decision making by clinical teams.

Because INB03 targets the
patient’s immune system and not the tumor, we believe INB03 is an immunotherapy that can be used to treat many types of hematologic
malignancies and solid tumors as part of combination therapy. The decision to use INB03 in a patient will be based on biomarkers that
should predict that a patient will benefit from treatment with the drug. We believe the ideal biomarker is easy to use and is determined
before treatment begins. MUC4 expression by epithelial tumors is an example of this type of biomarker. Our Phase I clinical trial preceded
the identification of MUC4 as a biomarker and focused on using determining the safety of INB03 as monotherapy in patients with advanced
solid tumors. This is a typical Phase I clinical trial design for first-in-man trials in cancer. We expect to use INB03 as part of combination
therapy with approved cancer therapies as part of Phase II development. We do not expect to need to modify INB03 therapy to treat each
different type of cancer, because INB03 therapy targets the immune system, not the cancer. We do expect to develop the INB03 beyond Phase
II to target a specific type of cancer to meet the current system of regulatory approval. For instance, INB03 may be approved to treat
patients with HER2+/MUC4+ breast cancer. To get subsequent approval for the treatment of patients with MUC4+ TNBC or MUC4+ pancreatic
cancer, we will need to perform a pivotal trial in patients with TNBC and pancreatic cancer respectively. After the first regulatory approval,
if and when achieved, we believe the difficulty and cost of achieving these labels extensions will decline with each successive approval.
At this time, we cannot predict if patients without biomarkers of inflammation, elevated MDSC or cytokines, or increased expression of
MUC4 will benefit from treatment with INB03. Those studies may be performed in the future, but they are not a current priority. We continue
to produce pre-clinical data for use of INB03 in cancer indications with a goal to find a development partner or out-license the program.
The Company does not have plans to perform clinical trials with INB03 at this time.
XPro
neutralizes soluble TNF in the brain in exactly the same way INB03 neutralizes soluble TNF in the tumor microenvironment but the effects
of soluble TNF neutralization in the brain are different. The cause of the destructive neuroinflammation in the brain are microglial
and astroglial cells. Glial cell are two of four cells in the neural unit that also includes oligodendrocytes and nerve cells. Activated
microglial cells are considered the resident macrophages of the brain. The primary role of microglial cells is to protect the neural
unit from infection. When innate immune dysfunction causes chronic inflammation, activated microglial cells produce soluble TNF that
activates astrocytes. Activated glial cells cause nerve cell and oligodrocyte dysfunction that results in synaptic pruning, nerve cell
death and demyelination of neurons. These pathologies contribute, in part, to neurodegenerative diseases such as AD, Parkinson’s
disease, ALS, MS, Huntington’s disease, glaucoma and TBI (traumatic brain injury) may contribute to neuropsychiatric diseases such
as depression, bi-polar disease, sleep disorders, autism, schizophrenia and PTSD. In the setting of AD, microglial activation causes
dendritic pruning, synaptic dysfunction and nerve cell death that contributes to cognitive decline and the behavioral manifestations
of AD including depression, aggressiveness, sleep disorders, hallucinations and anhedonia. Elimination of microglial activation should
reverse these symptoms. Because soluble TNF is the apex cytokine in the inflammatory cytokine cascade, neutralization of soluble TNF
with XPro should prevent glial activation and normalizes function of the neural unit.
The Company has completed
a Phase I trial using XPro to reverse neuroinflammation in patients with Alzheimer’s disease. The trial was performed in Australia
and was partially funded by a $1M USD Part-the-Cloud Award from the Alzheimer’s Association. The clinical trial was the first in
the Company’s development program for the treatment of dementia. The open label, dose escalation trial in patients with Alzheimer’s
disease with biomarkers of peripheral inflammation (one of CRP>1.5mg/L, HgbA1c>6.0, ESR>10sec or have ApoE4) treats the patients
with XPro as a once-a-week subcutaneous injection for 3 months. AD patients with one biomarker of inflammation are classified as having
AD with neuroinflammation (ADi). The company estimates this group of patients includes at least 40% of patients with AD. Patients have
multiple biomarkers of neuroinflammation tested before and during therapy including soluble biomarkers in blood and cerebral spinal fluid,
behavioral biomarkers (neuropsychiatric symptoms of AD), EEG and neuroimaging biomarkers using MRI. The primary goal of this short, open
label study was to demonstrate that treatment with XPro decreases neuroinflammation safely and to define the dose of XPro to use in the
Phase II trial.
The
Company is enrolling a global blinded randomized Phase II trial in ADi patients with Early AD in Australia (“AUS”), Canada
(“CAN”), the United Kingdom (“UK”), Spain (“ES”), France (“FR”), Germany (“DE”),
Poland (“PO”), the Czech Republic (“CZ”), Slovakia (“SL”) and the United States (“US”).
Early AD is patients that have MCI (Mild Cognitive Impairment) or mild AD. The XPro produced by KBI is being used in the Phase II trial.
After completion of the Phase II trial, patients will be offered to enroll in the Phase II open label extension trial (OLE). An Expanded
Access Scheme in patients who completed the Phase I trial in AUS. The goal of the Phase II trial will be to demonstrate the prolonged
control of neuroinflammation in patients with dementia will help control cognitive decline.
7
The Phase I trial enrolled 18 patients at doses
of 0.3, 0.6 and 1.0mg/kg given once a week as subcutaneous injection for three months. Patients in the 10mg/kg group were offered extended
use of the drug for up to 12 months. Three patients remained on XPro for 12 months. Preliminary data was presented in a webinar on 13
July 2020. Additional data was presented on January 21, 2021CSF cytokine/chemokines were measured in 9 patients before and after 12 weeks
of weekly therapy with XPro using a panel from OLINK Target 48 Cytokine (https://www.olink.com/products/olink-target-48-cytokine/),
that measures 45 (Figure AD1).
In the 6 patients in the 1mg/kg
per week dose, only one cytokine and chemokine, interferon gamma (“INFg”) did not change in the CSF of patients, the remainder
all decreased on average of 15%. The data analyzed provides evidence that XPro decreases neuroinflammation in patients with Alzheimer’s
disease.
We believe these data support the use of XPro to treat other diseases where
neuroinflammation is a part of the pathophysiology of the disease. The company studied the consequences of decreasing neuroinflammation
in the 6 patients from target dose group (XPro 1mg/kg for 12 weeks) be looking at the CSF proteome using technology for Proteome Sciences
using their TMT Calibrator™ platform. A large data set of proteins were identified. Early analysis of the data focusing on 26 AD
related proteins demonstrated changes in inflammation, neuronal and synaptic proteins caused by decreasing neuroinflammation after treatment
with XPro (Figure AD2). The proteome also demonstrated a clear dose response with a greater number of proteins being affected by the target
dose compared to low dose XPro therapy (0.3 vs 1.0 mg/kg/week for 12 weeks) (Figure AD3). The CSF proteome data is only partially analyzed.
Additional data may result from these ongoing analytics.

The
results of the Phase I study demonstrated that XPro safely decreases neuroinflammation in patients with ADi who have biomarkers of peripheral
inflammation or are ApoE4 positive when given for at least 3 months at the 1mg/kg once a week dose. Decreasing neuroinflammation with
XPro appears to decrease neurodegeneration and improve synaptic function and promote remyelination. The effect of XPro on the biology
and immunology of the brain in patients with AD suggest XPro therapy in patients with peripheral biomarkers of inflammation or ApoE4
allele(s) may impact cognitive decline. Although there were anecdotes of improved cognitive function in patients receiving the target
dose of XPro, this cannot be verified because the trial was not a blinded, randomized trial. The impact on cognition of controlling neuroinflammation
with XPro will be studied in the Phase II program which is a blinded randomized, placebo controlled clinical trial.
The ongoing blinded randomized
global Phase II trial in patients with early ADi will enroll 201 patients in a 2:1 ratio (XPro:placebo) at 1mg/kg once a week. The trial
is currently enrolling study subjects. Patients will be treated for 6 months. The primary end-point is Early/Mild Alzheimer’s Cognitive
Composite (EMACC), a sensitive cognitive end-point validated for use in patients with early AD. Secondary cognitive (ADAS-Cog13, CDR-SB
and NPI) and functional (GAS, ADCS-ADL) end-points will be measured. Exploratory structural and function biomarkers of brain function
and structural integrity using EEG and MRI DTI will be used in some or all patients. All patients will be eligible to continue XPro for
12 additional months in the Open Label Extension trial. Clinical and MRI metrics will be followed during the extension trial.
Effective
therapy for TRD is a large unmet need. Twenty percent of patients with a Major Depressive Disorder have TRD. Once third of TRD patients
have peripheral biomarkers to inflammation (elevated CRP). This is a large patient population. The role of TNF and anti-TNF therapeutics
was explored in a small open label clinical trial by Prof. Andrew Miller, MD of Emory University whereby it was demonstrated that patients
which have elevated TNF levels responded to treatment with infliximab (Miller, 2011).
The
Company received a $2.9M USD award from the National Institute of Mental Health (“NIMH”) to treat TRD with XPro. The blinded,
randomized Phase II trial will use biomarkers of peripheral inflammation to select patients with TRD for enrollment. Patients will be
treated for 6 weeks. Primary end-points include both clinical and neuroimaging measures. The final trial design is ongoing and discussions
with the FDA are not complete. The Company anticipates receiving authorization to initiate the clinical trial in 2H24. At which point
the Company may begin to request funds from the NIMH pursuant to the award.
INB03 and XPro are delivered
as a subcutaneous injection, similar to an insulin treatment or anti-obesity GLP-1 drugs, is given once a week. More frequent treatment
cannot be ruled out for future indications. Because this is a simple subcutaneous injection similar to an insulin injection (the therapy
patients give themselves for treatment of Type 1 diabetes mellitus), we expect patients to administer the therapy by themselves or caregivers
and not require expensive or logistically challenging clinic visits to receive the therapy.

Release
of INB03 and XPro drug supply
GMP DN-TNF product (INB03
and XPro) used in the oncology Phase I, AD Phase I and COVID-19 Phase II trial were manufactured by Lonza at a site in New Hampshire.
The supply of Lonza DN-TNF product is limited but allowed completion of the Phase I study in Alzheimer’s disease and support of
patients in the extension study for 12 months. New batches of XPro have been produced to support future clinical trials. The Company engaged
KBI Biopharma to manufacture 6 lots of XPro/INB03 at the Boulder, Colorado facility using the original master cell bank and updated manufacturing
process. One lot has been converted into drug product using the US fill/finish facility of Vetter Pharma. Half of the first lot is frozen
as drug substance at -80C with a plan to convert to drug product as clinical supplies are needed to support the AD and TRD Phase II trials
in May 2024. The unfrozen drug product is being used in the ongoing AD02 AD trial. The remainder of the original fermentation runs is
frozen as a cell paste with a plan to process to drug substance. The company expects to convert the drug substance to drug product 1H25.
Downstream processing to drug product and fill/finish to drug product of the cell paste will occur in 2025 as needed to support the clinical
trials. We plan to use a two-step approach to improve the yield of the drug substance from the fermentation process. The company has two
Phase III readiness programs in progress in preparation for the Phase III pivotal trial in patients with AD. The Company is working on
the yield of the drug product using the existing E.coli-based system. A second program is focused on down-stream process improvements
in the drug manufacturing program. Once the new strain and process is validated and functional, we will perform a manufacturing campaign
drug for future clinical trials. In the future, the Company may consider a strain change to improve yield of the fermentation step further.
The decision for strain improvements and strain change will be made in the future as clinical development programs proceed.
Interaction
with Regulatory Authorities Regarding INB03 and XPro Development
We have completed a Phase
I trial with INB03 in oncology. At this time we do not plan additional clinical trials with INB03 in oncology. A Phase I trial with XPro
in patients with Alzheimer’s disease is underway. The Phase II program with Alzheimer’s disease started during 2022. The Phase
I trial with XPro in patients with Alzheimer’s disease was performed in Australia under the regulatory authority of the TGA using
the Clinical Trials Exemption (“CTX”) scheme. Our first interaction with the regulatory body occurred in March 2018. The Company
received approval to initiate the Phase I trial with INB03 in patients with advanced solid tumors on May 21, 2018. The second interaction
with the regulatory body occurred in March 2019. The Company received approval to initiate the Phase I trial with XPro in patients
with Alzheimer’s disease in May 2019 and received authorization to start the Phase II trial in patients with mild AD on January
5, 2022. Our first interaction with the FDA occurred in July 2020 as part of the Phase II Quellor program to treat respiratory failure
in patients hospitalized with COVID-19 infection. The newly manufactured XPro is being used to support the Phase II AD trial and the Expanded
Access Scheme.
INB03 Product Development Path: Continued pre-clinical
studies to find a partner or out-license the progam
Phase I open label study in
patients with advanced solid tumors has been completed. All future cancer studies will use INB03 as part of combination therapy. The evolution
of oncology standard of care occurs quickly. Immune checkpoint inhibitors (“CPI”) were introduced 5 years ago. The success
of CPI change the focus of cancer therapy from cytotoxic based cancer regimens to immunotherapy-based cancer regimens. The approval of
Trastuzumab (“TDxd”) in 2022 had a similar effect on HER2 expressing cancers. For example, use of trastuzumab based therapy
in HER2+ breast cancer required 3+ expression of HER2. With TDxd, low HER2 expression (1+ or 2+ but not null) benefit for TDxd. This has
dramatically expanded the number of women eligible for trastuzumab based immunotherapy from 20% to half of women with breast cancer. This
dramatic change in breast cancer standard-of-care impacted our development plans for INB03 in breast cancer. The Phase II trial is planned
to be in women who have failed TDxd therapy. About half of women who receive TDxd are resistant to therapy. We believe, but need to confirm,
that many of those women express MUC4. We believe an exploratory, single arm open label Phase II in woman who progress after TDxd is warranted.
We believe the combination of TDxD, INB03 and TKI will be effective. We continue to conduct pre-clinical studies of INB03 in MUC4 expressing
tumors. The Company does not plan to perform further clinical studies with INB03 in oncology at this time. We continue to support pre-clinical
studies as we search for a partner or an out-licensing opportunity.
10
INB03 Pre-clinical Studies and/or Partnering
We plan to pursue an efficient
registration strategy using INB03 to improve the lives of patients with cancer and biomarkers of resistance such as MUC4. We believe that
this strategy has use across many types of solid tumors including patients who have failed CPI, tyrosine kinase inhibitors (“TKI”)
and anti-cancer antibody therapy such as trastuzumab monoclonal antibodies and trastuzumab based antibody drug conjugates. We have an
active partnering position as it relates to INB03 development in cancer, although limited partnering discussion are underway at this time
for INB03.
Our
INB03 platform can be used in cancer patients in many ways. The Phase I trial suggests the drug should not be used alone to treat cancer
but used in combination with, but not limited to, other cancer therapies including cytotoxic chemotherapy, immunotherapy, radiation and
surgery. We believe that INB03 can also be used to treat many types of hematologic and epithelial cancers.
XPro Regulatory Strategy
Drugs from the DN-TNF platform
will be developed using adequately powered, well designed studies with the goal to demonstrate a meaningful clinical benefit to patients.
Beyond Phase I, these will most often be blinded, randomized clinical trials using validated end-points that have been authorized by a
regulatory authority – the FDA, TGA, MHRA, EMA, etc. Currently, all planned studies will be performed in North America, AUS, EU
and/or the UK. Because there are no therapies similar to XPro approved in any market, we plan to take advantage of the regulatory opportunities
afforded to therapies that treat markets with a high unmet need. In the U.S., this includes Orphan Drug Designation and expedited programs
for approval including Accelerated Approval, Breakthrough Therapy Designation, Fast Track Designation, and priority review (see “Government
Regulation). We cannot predict which, if any, of these programs we will benefit from without further discussions with the FDA, EMA and
other competent regulatory authorities. A partner or licensee of INB03 may take a similar path to registration as XPro. The Company cannot
predict details of any INB03 registration strategy.
Immunotherapy
for Treatment of Alzheimer’s Disease
XPro
is being developed for the treatment of Alzheimer’s disease. Microglial activation and neuroinflammation are important causes of
the synaptic dysfunction and nerve cell death that causes cognitive decline in patient with dementia and Alzheimer’s disease. The
relationship between β amyloid plaques and tau neurofibrillary tangles, the traditional targets in AD drug development and neuroinflammation
is complex. We believe targeting plaques and tangles will have limited benefit. Targeting neuroinflammation, the common pathway leading
to synaptic dysfunction and nerve cell death, may be an effective treatment strategy. Substantial pre-clinical data supports the use
of XPro in murine models of AD. Substantial indirect data supports use of XPro in humans including a decreased risk of AD in patients
treated with non-selective TNF inhibitors for rheumatoid arthritis and treatment using direct injection into paraspinous venous plexus.
Because of different mechanism of action of XPro compared to the non-selective TNF inhibitors, we expect a lower risk of immunosuppression
and demyelinating complications such as multiple sclerosis (MS). The Company reported preliminary data on July 13, 2020 and January 21,
2021 supporting the use of XPro to decrease neuroinflammation in patients with Alzheimer’s disease and biomarkers of peripheral
inflammation (see above).
We completed enrollment of
patients into an open label, biomarker directed, Phase I clinical trial in AUS that approaches AD as an immunologic disease. Patients
with dementia with the diagnosis of AD with biomarkers of chronic inflammation that includes at least one of a hs-CRP>1.5 mg/L, a ESR>10
mm/h, a HbgA1C>6.0% or are ApoE4 positive were treated with XPro for 12 weeks. Three dosing cohorts were preformed – 0.3, 0.6
and 1.0 mg per week as a subcutaneous injection. Patients had multiple inflammatory biomarkers test before therapy, at 6 weeks and at
12 weeks. Biomarkers were reported in blood and cerebral spinal fluid. Experient biomarkers including MRI measures of white matter tract
neuroinflammation, axonal quality and axon myelin, and MRI measures of gray matter quality were included. Cognitive end-points were not
the focus of the Phase 1 clinical trial because of the wide range of disease severity enrolled and lack of a placebo group. Patients enrolled
in the Phase I trial had MMSE ranging from 24 to 12. This wide range of disease severity at the time of enrollment and the lack of a blinded
concurrent control group did not allow for determination of cognitive benefit beyond several anecdotal reports. The first patient was
enrolled in the low dose 0.3mg/kg/week cohort in the last week of November 2019. The Safety Review Committee met by teleconference on
January 7, 2020, to review the course of the patients in the first cohort and voted to open the second cohort, 1.0mg/kg/week, to enrollment.
The first patients were enrolled in the cohort the second week of February 2020. Based on preliminary data released on July 13, 2020,
and January 21, 2021, we closed after completion of a 0.6mg/kg treatment group. We canceled plans to treat patients with 3.0mg/kg. The
data from the Phase I trial informed the design of the Phase II trials described above.
11
XPro
Registration Studies and/or Partnering
We plan to aggressively pursue
an efficient registration strategy using XPro to improve the lives of patients with ADi. We define ADi as Alzheimer’s disease with
biomarkers of inflammation. We believe ADi is not the only indication for XPro in neurodegenerative and neuropsychiatric diseases. We
plan to pursue other indications in neurodegenerative diseases as resources become available. We have received NIMH funding to support
a Phase II TRD program that hopes to start patient enrollment in 2024. We have an active partnering position as it relates to XPro development
in neurodegenerative and neuropsychiatric diseases, although limited partnering discussion are underway at this time. There are two partnering
opportunities with this novel immunotherapy for the treatment of neurologic and psychiatric diseases. The first is a traditional partnership
focused on the developing the drug for all neurodegenerative and neuropsychiatric applications. The second is a more focused partnership
developing XPro as part of a combination therapy for a company’s existing therapy. After completion of proof-of-concept Phase II
studies, we will decide what the most efficient registration strategy is available to the company with XPro.
DN-TNF
for the treatment of Duchene Muscular Dystrophy
The
Company also is exploring partnership opportunities outside of neurodegenerative disease with DN-TNF such as DMD. DMD is a X-linked muscular
dystrophy that occurs in 1 in 3500 male births in the US. The disease is caused by defects in dystrophin, a protein needed for efficient
function of skeletal muscle. Boys with DMD develop skeletal muscle weakness that manifests early on with difficult standing and walking.
The boys become wheelchair bound by late adolescence and die of respiratory and cardiac failure in their twenties. There is no cure.
Symptomatic therapies include corticosteroids and novel strategies to replace dystrophin including ASO and gene therapies. Better therapies
are needed.
The
pathology of DMD is inflammation, skeletal muscle cell destruction, replacement of muscle fibers with fat and fibrosis. The most widely
used therapy, corticosteroids are focused on decreasing skeletal muscle inflammation. Although anti-inflammatory, corticosteroids cause
metabolic and immunologic problems including insulin resistance, obesity, hirsutism, short stature, depression and behavioral problems.
Long term use of corticosteroids exacerbates skeletal muscle weakness.
In
collaboration with Professor Armando Vallarta of University of California Irvine, the Company has completed and has ongoing studies with
DN-TNF in murine models of DMD. The animal models show that DN-TNF therapy decreases inflammation and muscle degradation, promotes muscle
regeneration and decreases fibrosis. This is a unique set of attributes compared to other therapies on the market or in development.
Because muscle cells produce TNF, we believe the benefits of DN-TNF therapy extends beyond the obvious immunologic attributes of modifying
T cell and macrophage infiltrates. Pre-clinical animal studies continue to better define the exact mechanism for these effects.
The
Company has filed global IP on the use of DN-TNF to treat muscular dystrophy. The Company has placed the IP and knowhow into a wholly
owned subsidiary called DN02, Inc. The purpose of this structure is to facilitate partnering and/or co-development of DN-TNF for DMD
in a way that does not complicate or compromise the development of XPro for CNS diseases. The Company is actively seeking a partner to
develop DN-TNF for DMD. We cannot predict if or when or under what terms a partnership will be formed.
12
INKmune:
Our NK cell Directed Product Candidate
INKmune
is our lead product candidate that converts the patient’s resting NK cells into cancer memory like NK cells, an essential step
to allow them to participate in the immune control of the patient’s cancer. We have shown this works ex vivo in human tissue cell
cultures, and we believe that this will work in vivo which is the purpose of our planned clinical trials.
Cancers grow and relapse because they evade the immune system. In many
cancers, NK cells are the most important cell for the elimination of residual disease that causes cancer relapse. NK cells target cells
based on a series of complex antigens on the cancer cell surface that signal the NK cells to activate and kill the cancer cell. NK cells
develop a memory like NK cell phenotype to enhance killing of cancer cells. This phenotype requires multiple simultaneous signals to be
delivered to the NK cells. A cocktail of three cytokines, IL12, IL15 and IL18 can be used to convert a resting NK cell to cytokine induced
memory like NK cells (“CIML”) [Fehneger 2016] or by INKmune priming with INB16 (TpNK – tumor primed NK cells). Although
the intracellular biology of these two strategies has yet to be worked out, they do not appear to be identical. In summary, INKmune converts
resting NK cells into tumor killing memory like NK cells that function well in the hostile environment of the TME. (Figure 1 below).
13
The ability of NK cells to kill tumor cells depends on the strength
and duration of the cell-cell interaction. This is called avidity. The higher the avidity the greater the tumor cell killing. Cytokine
stimulation may increase avidity of NK binding to some cancer cells whereas, in all experiments to date, INKmune priming enhances NK binding
to all cancer cells tested. The relative increase in avidity to specific cancer cells is cytokine specific; as shown below, IL15 increases
NK avidity for the ovarian cancer line SKOV-3 whereas IL2 has a limited effect. IL15 primed NK cells lyse SKOV-3 cells whereas IL2 primed
NK do not. INKmune primed NK (TpNK) showed the highest avidity for the tumor cells and the highest level of cytotoxicity. It is likely
that the use of multiple cytokines will achieve the same level of avidity and cytotoxicity as INKmune but studies with multiple cytokines
have not yet been performed (Figure below).
We
have demonstrated TpNK killing of many tumor types in laboratory studies. Tumor priming is effective regardless of the source of the
NK cells (normal volunteers or patients with cancer) and in many types of tumors – both cell lines and primary tumors from patients.
The principle of TpNK killing has also been demonstrated in two Phase I trials in patient with acute myelogenous leukemia (“AML”).
These trials were not supported by us and used a first-generation personalized cell therapy product and treatment strategy that is different
from the INKmune product and treatment strategy. In these trials, haplo-identical NK cells obtained from a first degree relative by leukapheresis
were primed ex-vivo using a lysate of the parent cell line from which we derived INB16 - INKmune. Once the TpNK therapy has been produced
and passed quality testing, the patient received conditioning therapy with chemotherapy (cyclophosphamide and fludarabine), the primed
haplo-identical NK cells were given to patients by intravenous infusion. Two Phase I clinical trials have been performed using that first-generation
adoptive cell therapy treatment strategy. An investigator-initiated trial performed at the Royal Free Hospital in London 2009 was funded
by a UK charity. Fifteen patients with relapsed, high-risk AML were enrolled in the trial. Because of drop-out due to disease progression,
delays in product production and complications of conditioning therapy, only 7 of the fifteen patients were treated with the TpNK cell
product. Four of seven patients showed clear benefit from the treatment with the TpNK product with prolonged relapse free remission and,
in one patient, conversion of a partial remission to full remission. None of the remissions were durable; all patients ultimately died
from disease progression. The safety of the product was found to be a combination of toxicity from the chemotherapy/radiotherapy conditioning
regimen and the TpNK therapy. In general, the complications were well tolerated although did require medical intervention including prolonged
periods of aplasia in two heavily pretreated patients that resolved with supportive care. The results of this study have been published
in a medical journal (PLoS One. 2015 Jun 10;10(6):e0123416. doi: 10.1371/journal.pone.0123416. eCollection 2015). In 2013, a second open
label, multi-center trial was performed in the US using the same product and procedures but targeting a slightly different patient population.
In the second trial, 12 patients in first remission with AML were treated with the haplo-identical TpNK product produced using the first
generation ex-vivo priming process. After conditioning with chemotherapy alone, the patients received TpNK in three dosing cohorts –
3x10^5, 1x10^6 or 3x10^6 TpNK per kilogram. Patients were followed for safety and relapse free survival. This trial confirmed the safety
of the TpNK treatment in patients with AML and reinforced many of the efficacy findings seen in the first trial with none of the previously
experienced side effects. Patients benefited from haplo-identical TpNK therapy with prolonged relapse free survival including two patients
that remain in remission more than 42 months after treatment. This trial has been published. (Biol Blood Marrow Transplant. 2018 Mar
26. pii: S1083-8791(18)30132-0. doi: 10.1016/j.bbmt.2018.03.019.) The results of the laboratory and Phase I studies provide evidence
that our strategy for treating residual disease is sensible but unproven.
14
Because
INKmune primes NK cells to target naturally occurring antigens, we believe INKmune can be used in to treat a wide variety of cancers
including hematologic malignancy (AML, MM, CML, high risk MDS) and solid tumors (renal, prostate, breast, ovarian, pancreas and lung).
We expect the list of INKmune sensitive tumors to continue to expand.
The primary role for INKmune
will be an immunotherapy targeting residual disease in patients after debulking cancer therapies such as cytotoxic chemotherapy and surgery.
At this time, we plan to give INKmune as monotherapy. We do not rule out the possibility of using INKmune as part of combination therapy
in the future. We do not expect to need to modify INKmune to treat these additional types of cancer, because we believe INKmune is a universal
cancer therapy where “one size fits all”. We believe for INKmune to receive regulatory approval for each cancer indication,
clinical trials will need to be performed which demonstrate its safety and effectiveness as a treatment for each such cancer. We believe
the difficulty and cost of achieving these labels extensions will decline with each successive approval, if and when achieved. For example,
if INKmune is proven to be effective therapy in patients with castration resistant prostate cancer, we will need to perform separate pivotal
trials for approval in lung, prostate or renal cancer.
Three
step process to preparation for INKmune human clinical trials:
INKmune
GMP scale-up for Phase I/II clinical material
The working cell banks and
individual INKmune product to be used in the patients for the clinical trial have been produced at the Centre for Cell, Gene & Tissue
Therapeutics at Royal Free Hospital / University College London to full cGMP (MHRA MIA(IMP)11149). All manufacturing has been under the
direction of Professor Mark Lowdell. The Company can produce enough INKmune to complete its Phase I clinical trial in men with metastatic
castrate resistant prostate cancer (mCRPC).. We have validated storage of INKmune for up over 3 years in vapor phase nitrogen and have
a fully scalable, closed system manufacturing process in validation which can produce up to 6 patient doses per week during phase I and
II trials. At intermediate scale we can manufacture 40 doses per week in a single 15-liter bioreactor. Importantly, we have validated
the storage of INKmune at -80 o C for up to 27 days which greatly facilitates the delivery and local storage of the drug for
clinical trials and post commercialization use. In contrast, as far as we know all other NK cell therapies and T cell therapies require
complex shipping of drug products in vapor phase nitrogen below -150 o C and specialized arrangements for ongoing storage at
the clinical sites. We may need additional INKmune for future clinical trials.
Interaction
with Regulatory Authorities Regarding INKmune Development
The INKmune Phase I studies
in high-risk MDS are being performed in the UK and Greece. We met with the Medicines and Healthcare Products Regulatory Agency (“MHRA”),
the UK version of the FDA as part of a Scientific Advice Meetings in preparation for submitting the CTA for our first planned program.
15
INKmune
Product Development Path Proposed Phase I Study in patients with high-risk MDS
During
2021, we initiated an open label Phase I cancer study in patients with high-risk myelodysplastic syndrome (“MDS”). Patients
are being enrolled who have a low burden of disease after completion of conventional therapy. The first patients were enrolled in the
first quarter of 2021. In the Phase I trial, patients with detectable residual disease in bone marrow and/or peripheral blood (<15%
blasts by conventional tests) will be treated with intravenous infusions of INKmune and monitored for changes in peripheral blood NK
activation, NK function and changes in residual blast counts in blood and bone marrow. We and others have previously shown that MDS patients
with inadequate NK function have statistically significantly poorer prognosis than matched patients with normal levels of NK function
(Tsirogianni et al 2019) and we have shown in laboratory experiments that the functional activity of NK cells from MDS patients can be
enhanced by exposure to INKmune. Moreover, INKmune-primed NK cells are not inhibited by the hypoxic conditions of the diseased bone marrow
microenvironment.
The
first patient was treated in the second quarter of 2021. The patient is now more than 12 months out from therapy with INKmune. The patient,
part of the first cohort, received 1x10^8 INKmune cells on day 1,8 and 15 as an in-patient. The patient did not require any type of conditioning
therapy or cytokine support. The patient tolerated the three infusions without any problems. The patient underwent intensive monitoring
over 120 days. There are 4 observations from this first patient. The patient has dramatically increased the number of activated, “memory-like”
NK cells in circulation. Memory-like NK cells (mlNK) are activated NK cells with a unique cell surface protein phenotype and which show
enhanced lysis of tumor cell in vitro. Post treatment with INKmune, elevated levels of mlNK cells were present in the patients in the
peripheral blood for more than 119 days when trial follow-up ceased. The patient mlNK actively kill NK resistant cancer targets in vitro.
Finally, the patient has had a significant clinical improvement with a reduction of his ECOG score from 2 to 0 and a significant reduction
in blood product support.
Three compassionate use cases
have also been treated. Two were young patients with AML who had failed previous hematopoietic stem cell transplants (“HSCT”).
The first compassionate-treatment patient showed such improved neutrophil and platelet counts that she was discharged from hospital for
the first time in six months. The second patient treated compassionately had failed two high risk HSCT and entered the course of INKmune
therapy with high percentage of blasts in his bone marrow. His blood NK cells responded in differentiation into mlNK as hoped but it is
too early to determine if INKmune has provide any clinical benefit. Due to market opportunities, the Company has closed the high-risk
MDS trial to focus on solid tumors. The Company plans to put all of its INKmune development efforts into the on-going US Phase I/II trial
in men with mCRPC.
16
INKmune
Registration Studies and/or Partnering
During March 2023 the Company opened an Investigational New Drug (“IND”)
application for a Phase I/II trial of INKmune in metastatic castrate resistant prostate cancer (mCPRC). The clinical trial is an open
label Phase I/II trial in men with metastatic castrate resistant prostate cancer. The trial has a modified Baysian design that allows
for a 3 patient Phase I for each dose level followed by a 6 patient Phase II trial. All patients will receive 3 infusions of INKmune on
days 1, 8 and 15. The three doses of INKmune at low, medium and high dose of INKmune is 1x10^8, 3x10^8 or 5 x10^8 cells per infusion respectively.
INKmune infusions are given as an out-patient with the use of pre-medication or additional cytokines. Patients are carefully monitored
for 6 months after the first dose of INKmune. There are four goals of the trial – determine safety in the target population; immunologic
efficacy, anti-tumor effects and select a dose for the pivotal trial. Immunologic efficacy is determined by an increase in the numbers
of memory like NK cells in the circulation of the patient and how long that increase lasts. In general, we are expecting the number of
mlNK to double and to persist in the circulation of the patient for more than 120 days. Anti-tumor effects will be monitored by serial
testing of blood prostatic surface antigen level (blood PSA), prostate-specific membrane antigen
nuclear medicine scan ( PMSA scan with piflufolastat F18; Pylarify®) and circulating tumor DNA. The Company enrolled the first
patient in the open label low dose Phase I cohorts of December 27, 2023. A second patient was enrolled in February 2024. The final patient
in the low dose cohort was enrolled in March 2024. The trial will enroll patients during all of 2024. The last patient in the Phase II
cohorts is expected to be enrolled in 1H25 with data lock 2H25. As an open label trial, there may be opportunities to see patient data
during 2024. Other solid cancers are of interest including nasopharyngeal cancer (“NPC”) which is a known target for NK cells
and an important unmet clinical need in emerging markets such as mainland China. Renal cell carcinoma is also a known target for INKmune.
We may seek to partner or sell INKmune. Although our development strategy is focused on North America and Europe, we believe INKmune will
also be attractive for markets on the Pacific Rim, South Asia and South America, but will wait for partners to help with the development
in those regions, however, at this time, we are not negotiating with any potential partners.
Importantly,
we have published data demonstrating INKmune efficacy at priming allogeneic NK cells ex-vivo (described above) and this includes priming
of NK cells differentiated from cord-blood derived hematopoietic stem cells (Domogala et al Cytotherapy 2017: 19:710-720). Numerous
companies are developing therapeutic strategies using cord blood derived NK cell products and one or more may wish to partner with us
to potentiate their product by co-incubation or co-administration with INKmune. We are also aware of companies developing cytokine primed
NK cells (CIML) for the treatment of cancer. We believe tumor primed NK cells are superior to ex vivo or in vivo cytokine strategies.
Challenges
in the Market for Our Product Candidates
The
market for new oncology therapies is competitive, complicated, and rapidly evolving. We will be competing with companies that are older,
larger, better financed and have greater experience. There are two types of drug companies – development companies and commercial
companies. Development companies take the risk of developing new products to proof-of-concept. Once proof-of-concept has been achieved,
if the drug provides clinical benefit, the product is usually acquired by a commercial company, which completes the drug’s clinical
development and markets the product. We are a development company which will seek to develop products such as INKmune from the bench
to the bedside to demonstrate proof-of-concept. The goal for us is to successfully develop such products to the point where they are
attractive targets for potential partners/acquirers.
According
to a recent Markets and Markets report, the immunotherapy market is growing rapidly at an annual rate of over 13%. Recently, the market
is biased towards T cell-based immunotherapies including bi-specific antibody therapies, checkpoint inhibitors and CAR-T cell-based therapies.
There are substantial numbers of clinical trials that are focused on the adaptive immune system versus clinical trials that are focused
on the innate immune system for the treatment of cancer. Our challenge will be to educate partners on the value of NK cell-based therapeutic
strategies. The need to educate people of the importance of INB03 is equally challenging. At the academic and investor level, there is
little recognition of the role MUC4 plays in causing resistance to immunotherapy. The concept of adding a drug to modify the immunosuppressive
environment of the TME to allow immunotherapy to be effective is also new. We will be responsible for educating them on the importance
of MUC4 expression, TAM, MDSC and why INB03 may be an important addition to the oncologist’s armamentarium. We believe educating
investors and partners about new therapeutic opportunities is an easier task than trying to differentiate our company from the many other
cancer immunotherapy companies. We plan to use a combination of publication, presentation and investor relations to discuss INKmune and
INB03 and to educate the clinical, biopharma and investor community on the value of these novel therapeutic approaches.
17
DN-TNF
Competition
To
our knowledge, there are no other companies developing a therapy to treat patients with MUC4+HER2+ tumors. This set of biomarkers predicts
a tumor that will be resistant to therapy. We believe MUC4 expression means that patient will be resistant to first line trastuzumab
based immunotherapy and will be resistant to CPI. INB03 is a unique category of cancer therapies. It is does not kill cancer cells. INB03
modulates the immunology of the TME to make existing therapies more effective. The advantage of this strategy is that it can be used
prospectively, and it does not add toxicity to existing therapy.
INKmune
Competition
Our
industry is highly competitive and subject to rapid and significant technological change. Our potential competitors include large pharmaceutical
and biotechnology companies, specialty pharmaceutical and generic drug companies, academic institutions, government agencies and research
institutions. We believe that key competitive factors that will affect the development and commercial success of our product candidates
are efficacy, safety, tolerability, reliability, price, and reimbursement level. Many of our potential competitors, including many of
the organizations named below, have substantially greater financial, technical, and human resources than we do and significantly greater
experience in the discovery and development of product candidates, obtaining FDA and other regulatory approvals of products and the commercialization
of those products. Accordingly, our competitors may be more successful than us in obtaining FDA approval for and achieving widespread
market acceptance of their drugs. Our competitors’ drugs may be more effective, or more effectively marketed and sold, than any
drug we may commercialize and may render our product candidates obsolete or non-competitive before we can recover the expenses of developing
and commercializing any of our product candidates. We anticipate that we will face intense and increasing competition as new drugs enter
the market and advanced technologies become available. Further, the development of new treatment methods for the conditions we are targeting
could render our drugs non-competitive or obsolete.
INKmune
is an immunotherapy that harnesses the biology of NK cells for the treatment of cancer. There is a long list of immunotherapy strategies
for the treatment of cancer and the immunotherapy for cancer market is growing rapidly. There are at least three ways to classify immunotherapy
for cancer. The list below classifies immunotherapy strategies beginning with those that are most closely related to INKmune:
1.
Companies in the NK cell
therapy business;
2.
Companies in the personalized
immune-oncology business; and
3.
Companies in the precision
immuno-oncology business.
18
We
are not aware of any approved treatments that are classified as NK cell therapies. We are aware of public companies in the NK cell therapy
business such as Century Therapeutics, Immunity Bio, Nkarta, Fate Therapeutics, Glycostem and others. These companies are developing
products that involve replacing or supplementing NK cells of the patient for the treatment cancer. Their product requires extensive ex-vivo
cell manipulations which, with respect to Century Therapeutics and Fate Therapeutics, may include gene therapy. The next larger group
of companies are in the personalized immuno-oncology business with products focused on T cell activation strategies. The most popular
are the CAR-T cell therapies which are a patient specific ex-vivo gene therapy approach to a single disease (for example: pediatric ALL).
CAR-T therapy has become wildly popular of late and includes many private companies, newer public companies such as Bluebird, Juno Therapeutics
and Mustang Bio as well as established companies such as Novartis and Gilead. For many of the companies, CAR-T cell therapies is their
only business. For the latter two, CAR-T cell therapies is a newly in-licensed program with marketing authorization in the US. Finally,
the precision immune-oncology category also includes companies with anti-cancer antibody products and the newer “check-point”
inhibitors. Antibody therapies are all about “illuminating” the cancer to the innate immune system (NK cells). Monoclonal
antibodies were the original immunotherapy that drove the growth of well-known biopharma companies including Genentech/Roche, Amgen,
Merck and others. Each of these products is disease specific (ie: treat only HER2+ breast cancer). Modern therapeutic antibodies are
much more complicated bi-specific and tri-specific antibodies that attempt to connect the cancer with activated T-cells of the adaptive
immune system. Check-point inhibitors are currently the most rapidly expanding product category in immuno-oncology. These CTLA-4 (ipilimumab)
and PD-1 inhibitors (pembrolizumab and nivolumab) specifically block a mechanism that shields cancers from T-cell killing. The two companies
in this business are Merck (pembrolizumab) and GSK (ipilimumab and nivolumab). There are many others trying to join this promising therapeutic
area including large companies such as BMS and Roche.
There
are several FDA approved drugs that improve the ability of the innate immune system (NK-cells) to treat cancer including mono-clonal
antibody therapies (for example: Rituximab®; Avastin® and Herceptin® marketed by Roche/Genentech); and “check-point”
inhibitors (Yervoy® and Opdivo®, BMS, Keytruda®, Merck and others). There is a large amount of development activity in the
immune checkpoint inhibitor field from both pharmaceutical giants including AstraZeneca, Merck & Co, Pfizer, Merck KGaA, Roche, GSK,
Novartis and Amgen and many start-ups, small companies and university spin-offs which have emerged in the past two years. Examples (in
alphabetical order) include Agenus, Alligator Bioscience, Ambrx, AnaptysBio, argenx, Bioceros, BioNovion, Cellerant Therapeutics, Checkpoint
Therapeutics, Compugen, CureTech, Enumeral, Five Prime Therapeutics, Genmab, GITR, ImmuNext, IOmet Pharma, iTeos Therapeutics, Jounce
Therapeutics, KAHR Medical, Multimeric Biotherapeutics, Nativis, Orega Biotech, Pelican Therapeutics, Pieris Pharmaceuticals, Prima BioMed,
Redx Pharma, Sorrento Therapeutics, Tesaro, TG Therapeutics, Theravectys and ToleroTech active in the field. The list of companies with
poly-specific antibodies that attempt to link the cancer with a cytotoxic T cell is long, includes both private and public companies
(Amgen, Xencor, F-Star, Merus and many others). Finally, two CAR-T cell therapies were recently approved for the treatment of ALL –
Kymriah™ (Novartis) and Yescarta™ (Gilead). We expect additional drugs to gain marketing authorization in the immune-oncology
space.
To our knowledge, there are no innate immune check-point inhibitors
in development that have the unique characteristics of INB03 that neutralize sTNF to: i) decreases the proliferation of MDSC; ii) decreasing
local and systemic immunosuppression caused by MDSC by stopping production of immunosuppressive cytokines and iii) improving NK/DC cross-talk
to recruit the adaptive immune system to fight the cancer.

Intellectual
Property
We seek to protect our therapeutic
programs by continuously developing patent properties covering novel compositions, formulations, purpose-limited compositions, combination
treatments, methods of medical treatment, and other inventions, whether created internally or in-licensed, in the United States Patent
& Trademark Office (the “USPTO”), the World Intellectual Property Organization (“WIPO”) under the Patent Cooperation
Treaty (“PCT”), and in patent offices for various foreign jurisdictions. While each invention is unique and territories for
protection are decided on a case-by-case basis, we generally pursue patents in Australia, Canada, Europe, Japan, and the United States,
and sometimes in Brazil, China and/or Korea. We currently have in our portfolio fifteen (15) issued patents and twenty-three (23) pending
patent applications, including both company-owned and in-licensed properties. The following sections and corresponding tables summarize,
for each of our current therapeutic programs, our pending and granted patent positions, to the extent publicly available, as of the time
of preparing this document:
DN-TNF
Platform Technology (Oncology, Central Nervous System Disorders, Acute and Chronic Peripheral Diseases)
The
DN-TNF Platform Technology covers a variety of dominant negative tumor necrosis factor (“DN-TNF”) variant proteins, including
the pegylated DN-TNF protein variants known as XPro and INB03. These DN-TNF protein variants can be considered a platform technology
for treating the underlying immune dysfunction associated with many disease manifestations. Unlike approved anti-TNF therapeutics, DNTNF
selectively targets and neutralizes soluble TNF, and is therefore not immunosuppressive. Additionally, XPro has been shown to cross the
blood brain barrier after peripheral administration, making it attractive for use in treating CNS disorders. The following table summarizes
current IP covering our DN-TNF Platform Technology:

INB-16
/ INKmune (Oncology)
INKmune
is a replication-incompetent derivative of our proprietary INB-16 cell line. One commercial application of INKmune includes use as a
therapeutic composition designed to enhance the ability of a patient’s own NK cells to seek, recognize and eliminate cancer. Another
commercial application of INKmune includes use as a cytokine-like (“pseudokine”) agent for enhancing NK cell killing specificity,
potency, and efficacy of NK cell -based therapeutics. INKmune, as a therapeutic, is intended for provision as an I.V. -infused product
containing replication-incompetent bio substrate units, each of which is adapted to present an aggregate of protein ligands and/or receptors
to a patient’s own NK cells, in vivo . Upon contacting the patient’s NK cells, INKmune converts resting NK cells into
what we call “primed” NK cells (“pNKs”). Data suggests that pNKs demonstrate enhanced killing of tumor cells,
thus INKmune may indirectly improve a patient’s own immune response to cancer. As a pseudokine agent, INKmune can be used to contact
the NK cells of an NK cell therapeutic product in vitro , e.g., during manufacturing, for enhancing characteristics of the NK cell
therapeutic and rendering an improved product. The following table summarizes current IP covering INB-16 / INKmune:

General
IP Disclosures
Our
commercial success depends in part on obtaining and maintaining patent and trade secret protections, where applicable, of our current
and future product candidates and the methods used to manufacture them, as well as successfully defending our patents against third-party
challenges.
Our
ability to stop third parties from making, using, selling, offering to sell or importing our products depends on the extent to which
we have rights under valid and enforceable patents or trade secrets that cover these activities, and whether we are able to enforce such
rights. We cannot assure you that our pending patent applications will result in issued patents, or that any or all rights will be enforceable
in every jurisdiction whether or not patent rights are sought.
International
PCT patent applications cover all 152 nations which are signatories of the PCT. However, our global IP strategy generally targets Australia,
Canada, Europe, Japan, and the United States, and sometimes Brazil, China and/or Korea, as targets for extending patent protection under
the PCT. Decisions regarding which countries to extend patent coverage under the PCT is taken on a case-by-case basis, subject to normal
business considerations such as value and return on investment. Given the markets for products we are developing, we consider the foregoing
jurisdictions to amount to “global” coverage as used herein as it relates to IP.
The
above disclosures related to patents and patent applications are subject to change based on strategic patent portfolio building decisions,
which may include refiling and reissue, certain abandonments, including those in favor of continuing patent applications, maturations
from provisional to non-provisional filings, and other regular patent prosecution activities.
Trademarks
The
designations INMUNE BIO TM , INB16 TM , INKmune TM , PSEUDOKINE TM , and XPro TM are trademarks
of INmune Bio, Inc. Some or all these trademarks may be protected by applications pending at the USPTO and other trademark registration
authorities globally. As part of the trademark registration process, we may be required to submit a statement of use evidencing bona
fide use of each mark in commerce. By nature of being in the biopharmaceutical business, certain regulatory requirements must be
met in connection with certain products and/or services prior to receiving marketing authorization from a regulatory agency, and thus
it may take some time before products and/or services are offered for sale and a statement of use can be submitted for perfecting trademark
registration. For these reasons, we may be required to obtain extensions of time, or to refile applications, seeking registration of
trademarks. We cannot guarantee that a given trademark application will be allowed or issued in a respective office for each jurisdiction.

law for the aid of debtors.
22
Xencor
License Agreement
On
October 3, 2017, the Company entered into a license agreement with Xencor, Inc. (“Xencor”), which has discovered and developed
a proprietary biological molecule that inhibits soluble tumor necrosis factor (the “Xencor Agreement”). During June 2021,
the Company entered into the First Amendment to License Agreement with Xencor. Pursuant to the Xencor Agreement, Xencor granted the Company
an exclusive worldwide, royalty-bearing license in licensed patent rights, licensed know-how and licensed materials (as defined in the
Xencor Agreement) to make, develop, use, sell and import any pharmaceutical product that comprises, contains, or incorporates Xencor’s
proprietary protein known as “XPro” that inhibits soluble tumor necrosis factor (or all modifications, formulations and variants
of the licensed protein that specifically bind soluble tumor necrosis factor) alone or in combination with one or more active ingredients,
in any dosage or formulation. The Xencor Agreement expires upon the later of: (a) the expiration of the last to expire valid claim covering
any pharmaceutical product that contains, comprises, or incorporates Xencor’s proprietary protein known as XPro alone or in combination
with one or more active ingredients, in any dosage or formulation. (“Licensed Product”) in such country or (b) ten years
following the first sale to a third party of the licensed product in such country. Net Sales with respect to any Licensed Product is
the gross amounts invoiced by us for sales of the Licensed Products less deductions actually incurred. A valid claim is an issued, unexpired
or pending claim with the patent rights that Xencor controls as of October 3, 2017 which patent rights are necessary to make, develop,
use, sell, have sold, offer for sale and import a Licensed Product in the Field (the Field means all applications for the treatment of
diseases in humans) or the Product Patent Rights, which claim has not lapsed, been abandoned, been revoked or been held to be unpatentable,
invalid or unenforceable by a final judgment of a court or other governmental agency or competent jurisdiction from which no appeal can
be or is taken within the time allowed for appeal and which has not been admitted to be invalid or unenforceable through reissue, re-examination,
disclaimer or otherwise. Product Patent Rights shall mean any and all our patent rights that are necessary to make, develop, use, sell,
have sold, offer for sale and import a Licensed Product in the Field, including any improvements or patent rights directed to the Licensed
Product. Either party may terminate the Xencor Agreement upon 60 days’ (10 days for any payment default) prior written notice to
the other party after the breach of any material provision of the agreement by the other party if the breaching party has not cured the
breach within the 60-day period (10-day period for any payment default) following written notice of termination by the non-breaching
party. We can terminate the Xencor Agreement upon 180 days prior written notice to Xencor. Xencor may terminate the Xencor Agreement
in its entirety or with respect to any specific Licensed Product upon written notice in the event that we contest, oppose or challenge
or assist any party in contesting, opposing or challenging, Xencor’s ownership of, or the enforceability or validity of the Patent
Rights that Xencor controls as of October 3, 2017 which Patent Rights are necessary to make develop, use, sell, have sold, offered for
sale and import a Licensed Product in the Field. Either party may terminate the Xencor Agreement upon written notice to the other party
upon or after the insolvency, bankruptcy, dissolution or winding up of such other party or the making or seeking to make or arrange an
assignment for the benefit of creditors of such other party or the initiation of proceedings in voluntary or involuntary bankruptcy which
proceeding, or action remains undismissed or unstayed for a period of more than 60 days.
In
consideration of the Xencor Agreement, we agreed to royalty payments and a percentage of any payments received in exchange for a sub-license.

INKmune
Research and Development
We
expect to use third parties to conduct our preclinical and clinical trials under the direct supervision of management.
INKmune
Manufacturing
We
intend to contract with third parties for the manufacture of our compounds for investigational purposes, for preclinical and clinical
testing and for any FDA approved products for commercial sale. Pre-clinical and clinical material for the early clinical trials with
INKmune has been manufactured under the direction of Mark Lowdell at a licensed Good Manufacturing Practice (“GMP”) facility.
The master cell bank, working cell bank and individual product doses were completed in July 2018. This clinical material is planned for
use in the Phase I/II clinical trials. As we progress in our clinical programs, additional working cell banks and therapeutic product
will be produced from the existing master cell bank. This process takes approximately 6 months and is not anticipated to delay the initiation
or enrollment of the Phase I/II trials. We may transfer the manufacturing to a different commercial contract manufacturing organization
after completion of these Phase II studies.
Human
Mesenchymal Stem Cells
In
November 2017 (amended in October 2022), we entered into a Material Transfer and License Agreement with the Anthony Nolan Cord Blood
Bank (“AN”), the oldest and largest non-directed cord blood bank in the United Kingdom for the supply the starting material
for the mesenchymal stem cells - umbilical cords not used after cord blood harvest. Mark Lowdell’s research group developed and
validated a methodology for producing large numbers of clinical-grade pooled human umbilical cord derived mesenchymal stem cells (“HucMSC”).
We believe we are well positioned to become a preferred manufacturing partner for companies who need MSC for clinical programs. Manufacture
of HucMSC is performed under the direction of Mark Lowdell in a licensed GMP facility that is contracted to the Company as part of existing
research and development agreements. The starting material for the HucMSC product is provided by the AN. The HucMSC product produced
in this facility are fully qualified to be used for either research or clinical trials. We have developed a validated manufacturing process
that reliably produces contract manufacturer of the clinical grade (“cGMP”) quality mesenchymal stem cells that we call CORDstrom.
To date, we are supporting two academic clinical trials with CORDstrom. One program is a in the UK treating children with erythematous
bullousa, a disfiguring skin disease in children that is similar to a second degree burn and treatment of system lupus in adults. Both
these studies are ongoing. INmune Bio is supplying the clinical product for treatment of these patients. The Company does not know the
results of these trials until they are announced by the principal investigators at the clinical sites. Currently, we plan to supply HucMSC
to third parties for their research use and in clinical trials as part of the development process for commercial pro/ducts. We may decide
to expand this agreement in the future if the commercial and/or development opportunities warrant such expansion. At the current time,
we expect this program to be funded by revenues from commercial sales. The agreement with AN terminates on November 29, 2027. AN may
terminate the license on written notice to us, if a donor withdraws consent to the continued use of umbilical cord tissue samples that
were obtained by AN. Additionally, either party may terminate the agreement on 30 days prior written notice to the other if that other
party materially breach any term of the agreement and such breaches (to the extent it is remediable) is not remedied within 30 days of
the written request to the other party to do so.

Challenges
in the Market for Immunotherapy Products
Government
Regulation
The
FDA and other federal, state, local and foreign regulatory agencies impose substantial requirements upon the clinical development, approval,
labeling, manufacture, marketing, and distribution of drug products. These agencies regulate, among other things, research and development
activities and the testing, approval, manufacture, quality control, safety, effectiveness, labeling, storage, record keeping, advertising
and promotion of our product candidates. The regulatory approval process is generally lengthy and expensive, with no guarantee of a positive
result. Moreover, failure to comply with applicable FDA or other requirements may result in civil or criminal penalties, recall or seizure
of products, injunctive relief including partial or total suspension of production, or withdrawal of a product from the market.
Various
regulatory authorities regulate, among other things, the research, manufacture, promotion, and distribution of drugs in the United States
under the FDA and other statutes and implementing regulations. The process required by the FDA before prescription drug product candidates
may be marketed in the United States generally involves the following:
●
completion
of extensive nonclinical laboratory tests, animal studies and formulation studies, all performed in accordance with the FDA’s
Good Laboratory Practice regulations;
●
submission
to the FDA of an investigational new drug application, or IND, which must become effective before human clinical trials may begin;
●
for
some products, performance of adequate and well-controlled human clinical trials in accordance with the FDA’s regulations,
including Good Clinical Practices, to establish the safety and efficacy of the product candidate for each proposed indication;
●
submission
to the FDA of a new drug application or NDA;
●
satisfactory
completion of an FDA preapproval inspection of the manufacturing facilities at which the product is produced to assess compliance
with current Good Manufacturing Practice, or cGMP, regulations; and
●
FDA
review and approval of the NDA prior to any commercial marketing, sale or shipment of the drug.
The
testing and approval process requires substantial time, effort and financial resources, and we cannot be certain that any approvals for
our product candidates will be granted on a timely basis, if at all.
Preclinical
tests include laboratory evaluations of product chemistry, formulation and stability, as well as studies to evaluate toxicity in animals
and other animal studies. The results of preclinical tests, together with manufacturing information and analytical data, are submitted
as part of an IND to the FDA. Some preclinical testing may continue even after an IND is submitted. The IND also includes one or more
protocols for the initial clinical trial or trials and an investigator’s brochure. An IND automatically becomes effective 30 days
after receipt by the FDA, unless the FDA, within the 30-day time period, raises concerns or questions relating to the proposed clinical
trials as outlined in the IND and places the clinical trial on a clinical hold. In such cases, the IND sponsor and the FDA must resolve
any outstanding concerns or questions before any clinical trials can begin. Clinical trial holds also may be imposed at any time before
or during studies due to safety concerns or non-compliance with regulatory requirements. An independent institutional review board, or
IRB, at each of the clinical centers proposing to conduct the clinical trial must review and approve the plan for any clinical trial
before it commences at that center. An IRB considers, among other things, whether the risks to individuals participating in the trials
are minimized and are reasonable in relation to anticipated benefits. The IRB also approves the consent form signed by the trial participants
and must monitor the study until completed.
The
FDA offers several regulatory mechanisms that provide expedited or accelerated approval procedures for selected drugs in the indications
on which we are focusing our efforts. These include accelerated approval under Subpart H of the agency’s NDA approval regulations,
fast track drug development procedures and priority review.
25
The United States, European
Union and other jurisdictions may grant orphan drug designation to drugs intended to treat a “rare disease or condition,”
which, in the United States, is generally a disease or condition that affects no more than 200,000 individuals. In the European Union,
orphan drug designation can be granted if: the disease is life threatening or chronically debilitating and affects no more than 50 in
100,000 persons in the European Union; without incentive it is unlikely that the drug would generate sufficient return to justify the
necessary investment; and no satisfactory method of treatment for the condition exists or, if it does, the new drug will provide a significant
benefit to those affected by the condition. If a product that has an orphan drug designation subsequently receives the first regulatory
approval for the indication for which it has such designation, the product is entitled to orphan exclusivity, meaning that the applicable
regulatory authority may not approve any other applications to market the same drug for the same indication, except in limited circumstances,
for a period of seven years in the United States and 10 years in the European Union Orphan drug designation does not prevent competitors
from developing or marketing different drugs for the same indication or the same drug for different indications. Orphan drug designation
must be requested before submitting an NDA. After orphan drug designation is granted, the identity of the therapeutic agent and its potential
orphan use are publicly disclosed. Orphan drug designation does not convey an advantage in, or shorten the duration of, the review and
approval process. However, this designation provides an exemption from marketing and authorization (NDA) fees. We plan to follow a similar
path with INB03 or XPro, although the precise indication cannot be determined until we are farther along in the development process.
Clinical
Trials
Phase
1 clinical trials typically involve the initial introduction of the product candidate into healthy human volunteers. In Phase 1 clinical
trials, the product candidate is typically tested for safety, dosage tolerance, absorption, metabolism, distribution, excretion and pharmacodynamics.
Phase
2 clinical trials are conducted in a limited patient population to gather evidence about the efficacy of the product candidate for specific,
targeted indications; to determine dosage tolerance and optimal dosage; and to identify possible adverse effects and safety risks.
Phase
3 clinical trials are undertaken to evaluate clinical efficacy and to test for safety in an expanded patient population at geographically
dispersed clinical trial sites. The size of Phase 3 clinical trials depends upon clinical and statistical considerations for the product
candidate and disease, but sometimes can include several thousand patients. Phase 3 clinical trials are intended to establish the overall
risk-benefit ratio of the product candidate and provide an adequate basis for product labeling.
Clinical
trials involve the administration of the product candidate to human subjects under the supervision of qualified medical investigators
according to approved protocols that detail the objectives of the study, dosing procedures, subject selection and exclusion criteria,
and the parameters to be used to monitor participant safety. Regulatory procedures differ in each country we will be working in. For
example, in the US, each protocol is submitted to the FDA as part of the IND for their review and consent before enrolling patients in
the clinical trial. The US is not the only place to perform clinical trials. Most countries have systems in place to allow academics
and companies to sponsor clinical trials of novel therapies in patients. For financial and technical reasons, the Company will perform
the Phase I clinical trials of our programs in the United Kingdom and Australia. The US will be included in the Phase II and//or Phase
III programs. Other venues such as Europe, Canada, Japan and other Pacific Rim countries may be included in the development program in
the future.
26
The INB03 Phase I trial has
been completed and provided evidence of safety and a pharmacodynamic drug affect, decrease of inflammatory biomarkers, needed to move
the program to a Phase II clinical trial in cancer. The Phase II clinical trial will combine INB03 with approved second line therapy in
patients with HER2+ breast cancer with or without brain metastasis that have progressed after treatment with TDxd. This is a combination
trial where the addition of INB03 to approved second line therapy may provide a therapeutic alternative in a disease without any drugs
approved. The Company has not lost interest in combining INB03 with immune checkpoint inhibitors (CPI), but competition for patients is
fierce in this arena. Our plan is to pursue treatment of tumors that express MUC4 as our lead indication. Tumors that express MUC4 are
resistant to all forms of immunotherapy due to a combination of increased MDSC in the tumor, decrease tumor macrophage (TAM) phagocytosis,
decreased inflammation in the tumor (a “cold” tumor) and direct effects of MUC4 and soluble TNF on HER2 function. If combination
therapy with INB03 decreases MUC4 expression and changes the TME to make the “cold” tumor “hot”, then addition
of a CPI will be warranted. At this time, the combination trial to treat MUC4+ TDxd resistant HER2+ expressing cancer is our most probable
registration strategy for INB03. This includes the combination of INB03 with trastuzumab antibody drug conjugate therapy TDxd in combination
with a TKI and/or CPI. Current therapies for TDxd resistant cancers are used on a trial by error approach. Using MUC4 expression as a
biomarker for to predict resistance may bring a precision medicine approach to this difficult clinical scenario. Addition of INB03 to
the treatment regimen for treating MUC4+ cancers may convert “cold” tumors to “hot” tumors making the eligible
for treatment with CPI. The design and successful completion of a Phase II trial is not guarantee of clinical relevance or commercial
viability. There are multiple therapies on the market or in development for the treatment of resistant breast cancer. The introduction
of TDxd to the clinician’s armamentarium is new and evolving. The future standard-of-care is not known. The registration and development
strategy for INB03 is multinational. The Phase II program may enroll patients in other countries, including the United States after submitting
an Investigational New Drug application, or IND, to the U.S. Food and Drug Administration, or FDA. If partnering is successful at any
stage of INB03 development, we expect the partner to influence the development and regulatory decisions needed with moving the drug to
commercialization. Finally, combination therapy to treat patients resistant to trastuzumab or CPI are not the only oncology application
for INB03. INB03 can be combined with other immune-oncology therapy to improve efficacy, safety or both. INB03 can be used as part of
combination therapy with immuno-oncology drugs, paired with tradition therapies such as cytotoxic chemotherapy, kinase inhibitors, cell
therapies or radiation therapy. The company is pursuing pre-clinical data in some of these areas. When and if positive developments occur,
we will communicate them to our shareholders. There are other regulatory venues that will be important for both our products – the
largest and most important is Europe. In Europe, the European Medicines Agencies (“EMA”) is responsible for authorization
of clinical trials in member states. In EU, there may be a requirement to get individual country authorization at the same time as EMA
authorization. The initial development of INB03 and XPro occurred in AUS followed by trials in other regulatory jurisdictions including
the US. The development of INKmune will start in the United Kingdom followed by trials in the US. XPro is being developed for the treatment
of Alzheimer’s disease under a Part-the-Cloud Award received Feb 2019. The biomarker directed Phase I trial was performed in AUS
using a regulatory strategy identical to that used for INB03 in cancer. Regulatory approval to initiate the trial was received on February
8, 2019. XPro treats microglial activation and innate immune dysregulation may be the cause with Alzheimer’s disease in some patients.
To our knowledge, there are few companies using an anti-inflammatory strategy for the treatment of Alzheimer’s disease. Those companies
include Denali Therapeutics (NASDAQ: DNLI); developing DNL747 that targets critical signaling proteins in the TNF pathway that regulate
inflammation and cell death. Alector (NASDAQ: ALEC) in partnership with Abbvie is developing AL002 that targets TREM2 on microglial cells.
Gliacure is targeting microglial cells in Alzheimer’s disease with a small molecule candidate GC021109.
Lecanemab
(Leqembi™; Eisai) was approved for the treatment of patients with Early AD in January 2023 This is this the second anti-amyloid
drug for the treatment of early AD to be approved. Donanemab (Lilly), a third drug anti-amyloid therapy for early AD is expected to be
approved 2Q24. These two drugs have similar efficacy and safety profiles. One of the common safety problems is the development of ARIA
(Alzheimer’s Related Imaging Abnormality) that causes a delay or discontinuation of therapy. ARIA is neuroinflammation related
side-effect more common in patients expressing ApoE4. The modest efficacy, sub-optimal safety and difficulty of use makes combination
therapy for the treatment of early AD an attractive development and therapeutic strategy. The Company is following the developments in
this area closely. The Company believes the anti-amyloid therapies will slowly develop market share, but due to their safety and efficacy
profile, there will be demand for safer and more efficacious therapies that do not target amyloid.
27
Clinical
testing must satisfy extensive FDA regulations. Reports detailing the results of the clinical trials must be submitted at least annually
to the FDA and safety reports must be submitted for serious and unexpected adverse events. Success in early-stage clinical trials does
not assure success in later stage clinical trials. The FDA, an IRB or we may suspend a clinical trial at any time on various grounds,
including a finding that the research subjects or patients are being exposed to an unacceptable health risk.
New
Drug Applications
Assuming
successful completion of the required clinical trials, the results of product development, preclinical studies and clinical trials are
submitted to the FDA as part of an NDA. An NDA also must contain extensive manufacturing information, as well as proposed labeling for
the finished product. An NDA applicant must develop information about the chemistry and physical characteristics of the drug and finalize
a process for manufacturing the product in accordance with cGMP. The manufacturing process must be capable of consistently producing
quality product within specifications approved by the FDA. The manufacturer must develop methods for testing the quality, purity and
potency of the final product. In addition, appropriate packaging must be selected and tested, and stability studies must be conducted
to demonstrate that the product does not undergo unacceptable deterioration over its shelf life. Prior to approval, the FDA will conduct
an inspection of the manufacturing facilities to assess compliance with cGMP.
The
FDA reviews all NDAs submitted before it accepts them for filing. The FDA may request additional information rather than accept an NDA
for filing. In this event, the NDA must be resubmitted with the additional information and is subject to review before the FDA accepts
it for filing. After an application is filed, the FDA may refer the NDA to an advisory committee for review, evaluation and recommendation
as to whether the application should be approved and under what conditions. The FDA is not bound by the recommendation of an advisory
committee, but it considers them carefully when making decisions. The FDA may deny approval of an NDA if the applicable regulatory criteria
are not satisfied. Data obtained from clinical trials are not always conclusive and the FDA may interpret data differently than we interpret
the same data. The FDA may issue a complete response letter, which may require additional clinical or other data or impose other conditions
that must be met in order to secure final approval of the NDA. If a product receives regulatory approval, the approval may be significantly
limited to specific diseases and dosages or the indications for use may otherwise be limited, which could restrict the commercial value
of the product. In addition, the FDA may require us to conduct Phase 4 testing which involves clinical trials designed to further assess
a drug’s safety and effectiveness after NDA approval and may require surveillance programs to monitor the safety of approved products
which have been commercialized. Once issued, the FDA may withdraw product approval if ongoing regulatory requirements are not met or
if safety or efficacy questions are raised after the product reaches the market.
Post-Approval
Requirements
Any
products manufactured or distributed by us pursuant to FDA approvals are subject to pervasive and continuing regulation by the FDA, including,
among other things, requirements relating to record-keeping, reporting of adverse experiences, periodic reporting, distribution, and
advertising and promotion of the product. After approval, most changes to the approved product, such as adding new indications or other
labeling claims, are subject to prior FDA review and approval. There also are continuing, annual user fee requirements for any marketed
products and the establishments at which such products are manufactured, as well as new application fees for supplemental applications
with clinical data. Pharmaceutical manufacturers and their subcontractors are required to register their establishments with the FDA
and certain state agencies and are subject to periodic unannounced inspections by the FDA and certain state agencies for compliance with
GMP, which impose certain procedural and documentation requirements upon us and our third-party manufacturers. Changes to the manufacturing
process are strictly regulated, and, depending on the significance of the change, may require prior FDA approval before being implemented.
FDA regulations also require investigation and correction of any deviations from cGMP and impose reporting requirements upon us and any
third-party manufacturers that we may decide to use. Accordingly, manufacturers must continue to expend time, money and effort in the
area of production and quality control to maintain compliance with cGMP and other aspects of regulatory compliance. If our future suppliers
are not able to comply with these requirements, the FDA may, among other things, halt our clinical trials, require us to recall a product
from distribution, or withdraw approval of the product.
28
The
FDA may withdraw approval if compliance with regulatory requirements and standards is not maintained or if problems occur after the product
reaches the market. Later discovery of previously unknown problems with a product, including adverse events of unanticipated severity
or frequency, or with manufacturing processes, or failure to comply with regulatory requirements, may result in revisions to the approved
labeling to add new safety information; imposition of post-market studies or clinical studies to assess new safety risks; or imposition
of distribution restrictions or other restrictions under a REMS program.
The
FDA closely regulates the marketing, labeling, advertising and promotion of pharmaceutical products. A company can make only those claims
relating to safety and efficacy, purity and potency that are approved by the FDA and in accordance with the provisions of the approved
label. The FDA and other agencies actively enforce the laws and regulations prohibiting the promotion of off-label uses. Failure to comply
with these requirements can result in, among other things, adverse publicity, warning letters, corrective advertising and potential civil
and criminal penalties. Physicians may prescribe legally available products for uses that are not described in the product’s labeling
and that differ from those tested by us and approved by the FDA. Such off-label uses are common across medical specialties. Physicians
may believe that such off-label uses are the best treatment for many patients in varied circumstances. The FDA does not regulate the
behavior of physicians in their choice of treatments. The FDA does, however, restrict manufacturer’s communications on the subject
of off-label use of their products.
Other
Healthcare Laws and Compliance Requirements
Our
sales, promotion, medical education, clinical research and other activities following product approval will be subject to regulation
by numerous regulatory and law enforcement authorities in the United States in addition to FDA, including potentially the Federal Trade
Commission, the Department of Justice, the Centers for Medicare and Medicaid Services, or CMS, other divisions of the U.S. Department
of Health and Human Services and state and local governments. Our promotional and scientific/educational programs must comply with the
federal Anti-Kickback Statute, the civil False Claims Act, physician payment transparency laws, privacy laws, security laws, and additional
federal and state laws similar to the foregoing.
The
federal Anti-Kickback Statute prohibits, among other things, the knowing and willing, direct or indirect offer, receipt, solicitation
or payment of remuneration in exchange for or to induce the referral of patients, including the purchase, order or lease of any good,
facility, item or service that would be paid for in whole or part by Medicare, Medicaid or other federal health care programs. Remuneration
has been broadly defined to include anything of value, including cash, improper discounts, and free or reduced-price items and services.
The federal Anti-Kickback Statute has been interpreted to apply to arrangements between pharmaceutical manufacturers on one hand and
prescribers, purchasers, formulary managers, and beneficiaries on the other. Although there are a number of statutory exceptions and
regulatory safe harbors protecting some common activities from prosecution, the exceptions and safe harbors are drawn narrowly. Practices
that involve remuneration that may be alleged to be intended to induce prescribing, purchases or recommendations may be subject to scrutiny
if they do not qualify for an exception or safe harbor. Failure to meet all of the requirements of a particular applicable statutory
exception or regulatory safe harbor does not make the conduct per se illegal under the federal Anti-Kickback Statute. Instead, the legality
of the arrangement will be evaluated on a case-by-case basis based on a cumulative review of all its facts and circumstances. Several
courts have interpreted the statute’s intent requirement to mean that if any one purpose of an arrangement involving remuneration
is to induce referrals of federal healthcare covered business, the federal Anti-Kickback Statute has been violated. The government has
enforced the federal Anti-Kickback Statute to reach large settlements with healthcare companies based on sham research or consulting
and other financial arrangements with physicians. Further, a person or entity does not need to have actual knowledge of the statute or
specific intent to violate it to have committed a violation. In addition, the government may assert that a claim including items or services
resulting from a violation of the federal Anti-Kickback Statute constitutes a false or fraudulent claim for purposes of the False Claims
Act. Many states have similar laws that apply to their state health care programs as well as private payors.
29
Federal
false claims and false statement laws, including the federal civil False Claims Act, or FCA, imposes liability on persons or entities
that, among other things, knowingly present or cause to be presented claims that are false or fraudulent or not provided as claimed for
payment or approval by a federal health care program. The FCA has been used to prosecute persons or entities that “cause”
the submission of claims for payment that are inaccurate or fraudulent, by, for example, providing inaccurate billing or coding information
to customers, promoting a product off-label, submitting claims for services not provided as claimed, or submitting claims for services
that were provided but not medically necessary. Actions under the FCA may be brought by the Attorney General or as a qui tam action by
a private individual in the name of the government. Violations of the FCA can result in significant monetary penalties and treble damages.
The federal government is using the FCA, and the accompanying threat of significant liability, in its investigation and prosecution of
pharmaceutical and biotechnology companies throughout the country, for example, in connection with the promotion of products for unapproved
uses and other illegal sales and marketing practices. The government has obtained multi-million and multibillion dollar settlements under
the FCA in addition to individual criminal convictions under applicable criminal statutes. In addition, certain companies that were found
to be in violation of the FCA have been forced to implement extensive corrective action plans, and have often become subject to consent
decrees or corporate integrity agreements, restricting the manner in which they conduct their business.
The
federal Health Insurance Portability and Accountability Act of 1996, or HIPAA, created additional federal criminal statutes that prohibit,
among other things, knowingly and willfully executing, or attempting to execute, a scheme to defraud any healthcare benefit program,
including private third-party payors; knowingly and willfully falsifying, concealing or covering up a material fact or making any materially
false, fictitious or fraudulent statement in connection with the delivery of or payment for healthcare benefits, items or services; and
willfully obstructing a criminal investigation of a healthcare offense. Like the federal Anti-Kickback Statute, the Affordable Care Act
amended the intent standard for certain healthcare fraud statutes under HIPAA such that a person or entity no longer needs to have actual
knowledge of the statute or specific intent to violate it in order to have committed a violation.
Given
the significant size of actual and potential settlements, we expect that the government will continue to devote substantial resources
to investigating healthcare providers’ and manufacturers’ compliance with applicable fraud and abuse laws. Also, many states
have similar fraud and abuse statutes or regulations that may be broader in scope and may apply regardless of payor, in addition to items
and services reimbursed under Medicaid and other state programs. Additionally, to the extent that our products, once commercialized,
are sold in a foreign country, we may be subject to similar foreign laws.
In addition, there has been a recent trend of increased federal and
state regulation of payments made to physicians and other healthcare providers. The Patient Protection and Affordable Care Act, as amended
by the Health Care and Education Reconciliation Act, or collectively, the Affordable Care Act, among other things, imposed new reporting
requirements on certain manufacturers of drugs, devices, biologics and medical supplies for which payment is available under Medicare,
Medicaid or the Children’s Health Insurance Program, with specific exceptions, for payments or other transfers of value made by
them to physicians and teaching hospitals, as well as ownership and investment interests held by physicians and their immediate family
members. Covered manufacturers are required to collect and report detailed payment data and submit legal attestation to the accuracy of
such data to the government each year. Failure to submit required information may result in civil monetary penalties of up to an aggregate
of $150,000 per year (or up to an aggregate of $1 million per year for “knowing failures”), for all payments, transfers of
value or ownership or investment interests that are not timely, accurately, and completely reported in an annual submission. Additionally,
entities that do not comply with mandatory reporting requirements may be subject to a corporate integrity agreement. Certain states also
mandate implementation of commercial compliance programs, impose restrictions on covered manufacturers’ marketing practices and/or
require the tracking and reporting of gifts, compensation and other remuneration to physicians and other healthcare professionals.
We
may also be subject to data privacy and security regulation by both the federal government and the states in which we conduct our business.
HIPAA, as amended by the Health Information Technology and Clinical Health Act, or HITECH, and their respective implementing regulations,
imposes specified requirements on certain health care providers, plans and clearinghouses (collectively, “covered entities”)
and their “business associates,” relating to the privacy, security and transmission of individually identifiable health information.
Among other things, HITECH makes HIPAA’s security standards directly applicable to “business associates,” defined as
independent contractors or agents of covered entities that create, receive, maintain or transmit protected health information in connection
with providing a service for or on behalf of a covered entity. HITECH also increased the civil and criminal penalties that may be imposed
against covered entities, business associates and possibly other persons, and gave state attorneys general new authority to file civil
actions for damages or injunctions in federal courts to enforce HIPAA and seek attorney’s fees and costs associated with pursuing
federal civil actions. In addition, certain states have their own laws that govern the privacy and security of health information in
certain circumstances, many of which differ from each other and/or HIPAA in significant ways and may not have the same effect, thus complicating
compliance efforts.
30
Coverage
and Reimbursement
Sales
of pharmaceutical products depend significantly on the extent to which coverage and adequate reimbursement are provided by third-party
payors. Third-party payors include state and federal government health care programs, managed care providers, private health insurers
and other organizations. Although we currently believe that third-party payors will provide coverage and reimbursement for our product
candidates, if approved, we cannot be certain of this. Third-party payors are increasingly challenging the price, examining the cost-effectiveness,
and reducing reimbursement for medical products and services. In addition, significant uncertainty exists as to the reimbursement status
of newly approved healthcare products. The U.S. government, state legislatures and foreign governments have continued implementing cost
containment programs, including price controls, restrictions on coverage and reimbursement and requirements for substitution of generic
products. Adoption of price controls and cost containment measures, and adoption of more restrictive policies in jurisdictions with existing
controls and measures, could further limit our net revenue and results. We may need to conduct expensive clinical studies to demonstrate
the comparative cost-effectiveness of our products. The product candidates that we develop may not be considered cost-effective and thus
may not be covered or sufficiently reimbursed. It is time consuming and expensive for us to seek coverage and reimbursement from third-party
payors, as each payor will make its own determination as to whether to cover a product and at what level of reimbursement. Thus, one
payor’s decision to provide coverage and adequate reimbursement for a product does not assure that another payor will provide coverage
or that the reimbursement levels will be adequate. Moreover, a payor’s decision to provide coverage for a drug product does not
imply that an adequate reimbursement rate will be approved. Reimbursement may not be available or sufficient to allow us to sell our
products on a competitive and profitable basis.
Healthcare
Reform
The
United States and some foreign jurisdictions are considering or have enacted a number of legislative and regulatory proposals to change
the healthcare system in ways that could affect our ability to sell our products profitably. Among policy makers and payors in the United
States and elsewhere, there is significant interest in promoting changes in healthcare systems with the stated goals of containing healthcare
costs, improving quality and/or expanding access. In the United States, the pharmaceutical industry has been a particular focus of these
efforts and has been significantly affected by major legislative initiatives.
By
way of example, in March 2010, the Affordable Care Act (“ACA”) was signed into law, intended to broaden access to health
insurance, reduce or constrain the growth of healthcare spending, enhance remedies against fraud and abuse, add new transparency requirements
for the healthcare and health insurance industries, impose new taxes and fees on the health industry and impose additional health policy
reforms. Among the provisions of the ACA of importance to our potential drug candidates are:
●
an
annual, nondeductible fee on any entity that manufactures, or imports specified branded prescription drugs and biologic agents, apportioned
among these entities according to their market share in certain government healthcare programs;
●
an
increase in the statutory minimum rebates a manufacturer must pay under the Medicaid Drug Rebate Program to 23.1% and 13.0% of the
average manufacturer price for branded and generic drugs, respectively;
●
a
new methodology by which rebates owed by manufacturers under the Medicaid Drug Rebate Program are calculated for drugs that are inhaled,
infused, instilled, implanted or injected;
●
a
new Medicare Part D coverage gap discount program, in which manufacturers must agree to offer 50% point-of-sale discounts off negotiated
prices of applicable brand drugs to eligible beneficiaries during their coverage gap period, as a condition for a manufacturer’s
outpatient drugs to be covered under Medicare Part D;
●
extension
of a manufacturer’s Medicaid rebate liability to covered drugs dispensed to individuals who are enrolled in Medicaid managed
care organizations;
●
expansion
of eligibility criteria for Medicaid programs by, among other things, allowing states to offer Medicaid coverage to additional individuals
and by adding new mandatory eligibility categories for certain individuals with income at or below 133% of the federal poverty level,
thereby potentially increasing a manufacturer’s Medicaid rebate liability;
31
●
expansion
of the entities eligible for discounts under the Public Health Service pharmaceutical pricing program; and
●
a
new Patient-Centered Outcomes Research Institute to oversee, identify priorities in, and conduct comparative clinical effectiveness
research, along with funding for such research.
In
addition, other legislative changes have been proposed and adopted since the ACA was enacted. These changes include, among others, the
Budget Control Act of 2011, which mandates aggregate reductions to Medicare payments to providers of up to 2% per fiscal year effective
April 1, 2013, and, due to subsequent legislative amendments, will remain in effect through 2024 unless additional Congressional action
is taken. In January 2013, President Obama signed into law the American Taxpayer Relief Act of 2012, which, among other things, further
reduced Medicare payments to several providers, including hospitals and cancer treatment centers, increased the statute of limitations
period for the government to recover overpayments to providers from three to five years. These new laws may result in additional reductions
in Medicare and other healthcare funding, which could have a material adverse effect on customers for our product candidates, if approved,
and, accordingly, our financial operations.
Since its enactment, there have been judicial, administrative, executive
and legislative challenges to certain aspects of the ACA. On June 17, 2021, the U.S. Supreme Court dismissed the most recent judicial
challenge to the ACA brought by several states without specifically ruling on the constitutionality of the ACA. Thus, the ACA will remain
in effect in its current form. Further, prior to the U.S. Supreme Court ruling, President Biden issued an executive order to, among other
things, instruct certain governmental agencies to review and reconsider their existing policies and rules that limit access to health
care, including among others, reexamining Medicaid demonstration projects and waiver programs that include work requirements, and policies
that create unnecessary barriers to obtaining access to health insurance coverage through Medicaid or the ACA.
On
March 11, 2021, President Biden signed the American Rescue Plan Act of 2021 into law, which eliminates the statutory Medicaid drug rebate
cap, currently set at 100% of a drug’s average manufacturer price, for single source and innovator multiple source drugs, beginning
January 1, 2024. Payment methodologies may also be subject to changes in healthcare legislation and regulatory initiatives. For
example, Centers for Medicare and Medicaid Services may develop new payment and delivery models, such as bundled payment models. There
also has been heightened governmental scrutiny in the United States of pharmaceutical pricing practices in light of the rising cost of
prescription drugs and biologics. Such scrutiny has resulted in several recent U.S. Congressional inquiries and proposed and enacted
federal and state legislation designed to, among other things, bring more transparency to drug pricing, reduce the cost of prescription
drugs under Medicare, review the relationship between pricing and manufacturer patient programs and reform government program reimbursement
methodologies for drugs. By way of example, in August 2022, the Inflation Reduction Act of 2022, or the IRA, was signed into law. Among
other things, the IRA requires manufacturers of certain drugs to engage in price negotiations with Medicare (beginning in 2026), with
prices that can be negotiated subject to a cap; imposes rebates under Medicare Part B and Medicare Part D to penalize price increases
that outpace inflation (first due in 2023); and replaces the Part D coverage gap discount program with a new discounting program (beginning
in 2025). The IRA permits the Secretary of the Department of Health and Human Services to implement many of these provisions through
guidance, as opposed to regulation, for the initial years. For that and other reasons, it is currently unclear how the IRA will be effectuated,
or the impact of the IRA on our business.
At
the state level, legislatures in the United States have also increasingly passed legislation and implemented regulations designed to
control pharmaceutical product pricing, including price or patient reimbursement constraints, discounts, restrictions on certain product
access and marketing cost disclosure and transparency measures and, in some cases, designed to encourage importation from other countries
and bulk purchasing. In addition, regional healthcare authorities and individual hospitals are increasingly using bidding procedures
to determine what pharmaceutical products and which suppliers will be included in their prescription drug and other healthcare programs.
We
expect that the ACA, as well as other healthcare reform measures that may be adopted in the future, may result in more rigorous coverage
criteria and lower reimbursement, and in additional downward pressure on the price that we receive for any approved product. Any reduction
in reimbursement from Medicare or other government-funded programs may result in a similar reduction in payments from private payors.
The implementation of cost containment measures or other healthcare reforms may prevent us from being able to generate revenue, attain
profitability or commercialize our drugs.
Human
Capital Resources
As
of December 31, 2023, we had 11 full-time employees and 6 part-time employees. We consider the intellectual capital of our employees
to be an important driver of our business and key to our future prospects. We monitor our compensation programs closely and provide what
we consider to be a very competitive mix of compensation and insurance benefits for all our employees, as well as participation in our
equity programs. None of our employees is subject to a collective bargaining agreement or represented by a trade or labor union. We consider
our relations with our employees to be good.
